Beyond the Answer

Para resolverlo, podemos utilizar el principio de inclusión-exclusión. Si tenemos 18 personas que van al cine y 15 que van al teatro, podemos sumar estas cifras: 18 + 15 = 33. Sin embargo, tenemos un total de solo 25 encuestados, lo que significa que hay personas que asisten a ambos lugares. Si restamos el total de encuestados a la suma anterior, 33 - 25 = 8, esto indica que 8 personas asisten tanto al cine como al teatro. Por lo tanto, la respuesta es que 8 personas asisten a ambos lugares. ¡Sencillo y festivo!

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.

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.)

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.

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.
