For the 100 systolic blood pressure levels listed in the accompanying data set, the mean is 125.46000 mm Hg and thestandard deviation is 17.08412 mm Hg. Assume that a simple random sample has been selected. Use a 0.05 significance level to test the claim that the sample is from a population with a meangreater than 120 mm Hg.Click the icon to view the data set of systolic blood pressure levels.Identify the null and alternative hypotheses.Ho:H₁:(Type integers or decimals.

The percentage of complete passes is an important measure for a quarterback in the NFL. A particular quarterback has a career completion percentage of 55%. The quarterback got a new coach and then played a few games where he completed 48 of 100 passes. a. Specify the null and alternative hypotheses to determine whether the proportion of completed passes has decreased with the new coach. b. Calculate the value of the test statistic and the p-value. c. At the 5% significance level, can you conclude that the quarterback's completion percentage has decreased? How do I solve this in excel?
