The mean is 40.6.

Solución

To find the mean, add all the numbers and then divide by the total count. Numbers: 56, 42, 37, 29, 45, 51, 30, 25, 34, 57 Step 1: Sum the numbers: 56 + 42 = 98 98 + 37 = 135 135 + 29 = 164 164 + 45 = 209 209 + 51 = 260 260 + 30 = 290 290 + 25 = 315 315 + 34 = 349 349 + 57 = 406 Step 2: Divide the sum by the number of data values (10): 406 / 10 = 40.6 Thus, the mean is 40.6.

Bonus Knowledge

To find the mean, add all the numbers together and then divide by the total count of the numbers. Adding up: \( 56 + 42 + 37 + 29 + 45 + 51 + 30 + 25 + 34 + 57 = 405 \). There are 10 numbers in total, so divide 405 by 10. Mean = \( \frac{405}{10} = 40.5 \). It seems that none of the provided options match the calculated mean of 40.5. Let's check those options again for accuracy.

Question 4(Multiple Choice Worth 2 points) (04.01 MC) FreezeFrame, a social networking site, sent out a survey in which the users simply click a response to join the sample. One of the questions in 2015 was, "Do you prefer to shop online?" More than 45,000 people responded, with \( 79 \% \) responding yes. What can you conclude from the survey? About 79\% of people planned to shop online in 2015. The poll used a convenience sample, so the results tell us little about the population of all adults. The poll used voluntary response, so the results tell us little about the population of all adults. The sample is too small to draw any conclusions. None of the previous answers is correct.

Question 5 (Muttiple Choice Worth 2 points) (04.01 LC) Each person in a simple random sample of 1,200 received a survey, and 325 people returned their survey. How could nonresponse cause the results of the survey to be biased? Those who did not respond reduced the sample size, and small samples have more bias than large samples. Those who did not respond may differ in some important way from those who did respond. Those who did not respond caused a violation of the assumption of independence. Those who did not respond are indistinguishable from those who did not receive the survey. Those who did not respond represent a stratum, changing the random sample into a stratified random sample.
