A survey asked people if they were aware that maintaining a healthy weight could reduce the risk of stroke. A 95% confidence interval was found using the survey results to be (0.54, 0.62). What is the correct interpretation of this interval? A)There is a 95% chance that the sample proportion of people that are aware that maintaining a healthy weight could reduce the risk of stroke is between 0.54 < p < 0.62. B)There is a 95% chance that the...

In a survey, 500 adults in a certain country were asked how many hours they worked in the previous week. Based on the results, a 95% confidence interval for mean number of hours worked was lower bound: 37.1 and upper bound: 38.9. Which of the following represents a reasonable interpretation of the result? For those that are not reasonable, explain the flaw. Complete parts (a) through (d) below. (a) There is a 95% chance the mean number of hours worked...
