A survey of 1010 college seniors working towards an undergraduate degree was conducted. Each student was asked, "Are you planning or not planning to pursue a graduate degree?" Of the 1010 surveyed, 658 stated that they were planning to pursue a graduate degree. Construct and interpret a 98% confidence interval for the proportion of college seniors who are planning to pursue a graduate degree. (0.616,0.686): we are 98% confident that the proportion of college seniors who are planning to pursue...

Chapter 10, Testbank, Question 009-013 A sample of S2 female workers and another sample of 64 male workers from a state produced mean weekly earnings of $742.49 for the females and $764.78 for the males. Suppose that the standard deviations of the weekly earnings are $86.88 for the females and $96.38 for the males. The null hypothesis is that the mean weekly earnings are the same for females and males, while the alternative hypothesis is...

A survey asked, "How many tattoos do you currently have on your body?" Of the 1223 males surveyed, 186 responded that they had at least one tattoo. Of the 1032 females surveyed, 130 responded that they had at least one tattoo. Construct a 99% confidence interval to judge whether the proportion of males that have at least one tattoo differs significantly from the proportion of females that have at least one tattoo. Interpret the interval. Let p1 represent the proportion...
