**Problem 4: Hypothesis Testing on ACT Composite Scores**ACT composite scores are normally distributed with a population mean (\( \mu \)) of 21. A sample of 25 students is randomly selected from a local high school, yielding a sample mean (\( \bar{X} \)) of 23 and a sample standard deviation (\( s \)) of 5.2. **Research Question:**Do the data support the claim that the average ACT composite score of students from this high school is different from 21? Test this hypothesis at the \( \alpha = 0.05 \) significance level.

The mean number of sick days an employee takes per year is believed to be about 10. Members of a personnel department do not believe this figure. They randomly survey 8 employees. The number of sick days they took for the past year are as follows: 10; 5; 13; 3; 11; 8; 6; 9. Let X = the number of sick days they took for the past year. Should the personnel team believe that the mean number is about 10? Conduct a hypothesis test at the 5% level.Note: If you are using a Student's t-distribution for the problem, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.) What is the test statistic? (If using the z distribution round your answers to two decimal places, and if using the t distribution round your answers to three decimal places.) t = Construct a 95% confidence interval for the true mean.

Suppose IQ scores were obtained for 20 randomly selected sets of siblings. The 20 pairs of measurements yield x = 101.13, y = 103.5, r=0.867, P-value = 0.000, and y = 6.25 +0.96x, where x represents the IQ score of the younger child. Find the best predicted value of y given that the younger child has an IQ of 101? Use a significance level of 0.05.
