In a recent survey of full-time female workers, 43% said that they would rather give up some of their salary for more personal time. Suppose you select a sample of 100 full-time female workers.
A. What is the probability that in the sample, fewer than 50% would rather give up some of their salary for more personal time?
B. What is the probability that in the sample, between 40% and 50% would rather give up some of their salary for more personal time?
C. What is the probability that in the sample, more than 39% would rather give up some of their salary for more personal time?

In a survey of 1000 women age 22 to 35 who work full time, 555 indicated that they would be willing to give up some personal time in order to make more money. The sample was selected in a way that was designed to produce a sample that was representative of women in the targeted age group. (a) Do the sample data provide convincing evidence that the majority of women age 22 to 35 who work full-time would be willing...

In a recent survey, 43% indicated chocolate was their favorite flavour of ice cream. Suppose that we select a sample of 12 people and ask them to name their favourite flavour of ice cream. a. How many of those in the sample would you expect to name chocolate? (Round the final answer to 2 decimal place.) Probability b. What is the probability exactly six of those in the sample name chocolate? (Do not round the intermediate values....
Some college graduates employed full-time work more than 40 hours per week, and some work fewer than 40 hours per week. We suspect that the mean number of hours worked per week by college graduates, A. is greater than 40 hours and wish to do a statistical test. We select a random sample of college graduates employed full-time and find that the mean of the sample is 44 hours and that the standard deviation is 4 hours Based on this...
Some college graduates employed full-time work more than 40 hours per week, and some work fewer than 40 hours per week. We suspect that the mean number of hours worked per week by college graduates, , is different from 40 hours and wish to do a statistical test. We select a random sample of college graduates employed full-time and find that the mean of the sample is 36 hours and that the standard deviation is 3 hours. Based on this...
