An article in the San Jose Mercury News stated that students in the California state university system take 5 years, on average, to finish their undergraduate degrees. A freshman student believes that the mean time is less and conducts a survey of 38 students. The student obtains a sample mean of 4.4 with a sample standard deviation of 0.3. Is there sufficient evidence to support the student's claim at an α=0.01α=0.01 significance level? Determine the test statistic. Round to four...

It is believed that nearsightedness affects about 8% of all children. In a random sample of 194 children, 21 are nearsighted. 1. What proportion of children in this sample are nearsighted? (round to four decimal places) 2. Given that the standard error of the sample proportion is 0.0195 and the point estimate follows a nearly normal distribution, calculate the test statistic (use the Z-statistic). Z =  (please round to two decimal places) 3. What is the p-value for this hypothesis test?...
