The Deep Dive

To find the range of Ravi's quiz scores, you subtract the lowest score from the highest score. In this case, the lowest score is 67, and the highest score is 86. So, the range would be \(86 - 67 = 19\). This means Ravi's performances varied by 19 percentage points, a reflection of his quiz consistency or fluctuations. Understanding the range is crucial in statistics, as it gives a quick sense of dataset spread. However, it’s important to note that the range can be heavily influenced by outliers, so considering other measures of spread like variance and standard deviation is beneficial. This broader perspective helps paint a clearer picture of data distribution beyond just the extremes!

1 Multiple Answer 2 points What does it mean to be \( 95 \% \) confident when referencing confidence intervals? Select all that apply. The \( 95 \% \) is a success rate of the process of computing the confidence interval that contain the parameter. The \( 95 \% \) refers to the percentage of ALL possible samples resulting in a confidence interval that contains the parameter. It is a range of values between which all values of the variable will lie. This is the probability that the parameter lies in the confidence interval. Then

A report claims that the returns for the investment portfolios with a single stock have a standard deviation of 0.58 , while the returns for portfolios with 35 stocks have a standard deviation of 0.326 . Explain how the standard deviation measures the risk in these two types of portfolios. Choose the correct answer below. A. A lower standard deviation means less certainty in the return and more risk. Hence, the returns for portfolios with 35 stocks have more risk than the ones with a single stock. B. Compare the ratio of the standard deviation to the number of stocks for each type of portfolio. If the ratio is smaller, than the risk is higher. Hence, the returns for portfolios with 35 stocks have more risk than the ones with a single stock. C. A lower standard deviation means more certainty in the return and less risk. Hence, the returns for portfolios with 35 stocks have less risk than the ones with a single stock. D. Compare the ratio of the standard deviation to the number of stocks for each type of portfolio. If the ratio is smaller, than the risk is higher. Hence, the returns for portfolios with 35 stocks have less risk than the ones with a single stock. E. They both have the same risk because the difference in the standard deviation is too small.

Decide whether the following statement makes sense (or is clearly true) or does not make sense (or is clearly false). Explain your reasoning. Both exams had the same range, so they must have had the same median. Choose the correct answer below. A. This does not make sense because the range is the most common value or group of values in a distribution. It has nothing to do with the median. B. This makes sense because the median is equal to the range. C. This makes sense because the median is equal to half of the range. D. This does not make sense because the range is the difference between the highest and lowest data values. It has nothing to do with the median.

ariation ach night you total the day's sales and the total volume of ice cream sold in your shop. You notice that when an employee named Ben works, the mean price of the ice cream sold is \( \$ 2.20 \) per pint ith a standard deviation of \( \$ 0.10 \). On nights when an employee named Jerry works, the mean price of the ice cream sold is \( \$ 2.25 \) per pint with a standard deviation of \( \$ 0.35 \). Which employee likely ceives more complaints that his servings are too small? Explain. A. The means are nearly equal. However, because Ben's standard deviation is smaller, he likely serves more small portions. B. Jerry likely serves more small portions because he has a smaller mean. C. The means are nearly equal. However, because Jerry's standard deviation is larger, he likely serves more small portions. D. Ben likely serves smaller portions because he has a smaller mean. h. Bert answer below.

Describe the process of calculating a standard deviation. Give a simple example of its calculation (such as calculating the standard deviation of the numbers \( 2,3,4,4 \), and 6 ). What is the standard deviation if all of the sample values are the same? Fill in the blanks to complete the process of calculating a standard deviation. Compute the mean of the data set. Then find the deviation from the mean for every data value by subtracting the mean from the data value. Find the squares of all the deviations from the mean, and then add them together. Divide this sum by the total number of data values minus 1 . The standard deviation is the square root of this quotient. The standard deviation of the numbers \( 2,3,4,4 \), and 6 is approximately (Round to three decimal places as needed.)

Points: 0 of 1 After recording the pizza delivery times for two different pizza shops, you conclude that one pizza shop has a mean delivery time of 46 minutes with a standard deviation of 5 minutes. The other shon has a mean delivery time of 42 minutes with a standard deviation of 21 minutes. Interpret these figures. If you liked the pizzas from both shops equally well, which one would you order from? Why? Interpret these figures. Choose the correct answer below. A. Both the means and the variations are nearly equal. B. The means are nearly equal, but the variation is significantly greater for the second shop than for the first. C. The variations are nearly equal, but the mean is greater for the first shop than for the second. D. The means are nearly equal, but the variation is significantly lower for the second shop than for the first. If you liked the pizzas from both shops equally well, which one would you order from? Why? Choose the correct answer below. A. Choose the second shop. The delivery time is more reliable because it has a larger standard deviation. B. Choose the first shop. The delivery time is more reliable because it has a lower standard deviation. C. Choose the first shop. The delivery time is more reliable because it has a lower mean. D. Choose the second shop. The delivery time is more reliable because it has a larger mean.
