Suppose the 99% confidence interval for the mean SAT scores of applicants at a business college is given by [1,695, 1,840]. Thisconfidence interval uses the sample mean and the sample standard deviation based on 25 observations. What are the sample meanand the sample standard deviation used when computing the interval?Note: Round "Sample mean" to 1 decimal place and "Sample standard deviation" to 2 decimal places.> Answer is complete but not entirely correct.Sample meanSample standard deviation1,767.5259.21 x

Given that,The 99% confidence interval is (1695,1840)and sample size (n) = 25

This problem is fill in the blank. Just choose the correct answers. Thank you for your help A scientist has read that the mean birth weight, μ, of babies born at full term is 7.2 pounds. The scientist, believing that μ is less than this value, plans to perform a statistical test. She selects a random sample of birth weights of babies born at full term and finds the mean of the sample to be 6.9 pounds and the standard deviation to be 1.7 pounds. Based on this information, answer the questions below. What are the null hypothesis (H0) and the alternative hypothesis (H1) that should be used for the test? H0: (choose one) less than, less than or equal to, greater than, greater than or equal to, equal to, or not equal to.      (choose one)      6.9 pounds, 7.2 pounds, or 1.7 pounds. H1: (Choose one) less than, less than or equal to, greater than, greater than or equal to, equal to, or not equal to.          (Choose one)     6.9 pounds, 7.2 pounds, or 1.7 pounds. In the context…
