You're fired! ~ Suppose that in a random sample of 252 employed Americans, there are 38 individuals who say that they would fire their boss if theycould.Round all calculated values in this problem to 4 decimal places.1. The value 38/252 = 0.1508 is a StatisticWe want to use the information from the sample to conduct a hypothesis test to determine if fewer than 19% of employed Americans would fire theirboss if they could.2. Choose the null and alternative hypotheses for this test. Use appropriate notation.ОА. Но : р %3D 0.19, На : р <0.19В. Но : р %3D 0.19, На : р#0.19С. Но : р %3D 0.19, На : р<0.1508OD. Ho : p = 0.19, HA : p > 0.19A3. If you assume that the observations in the sample are independent, what is the smallest value the sample size could be to meet the conditions forthis hypothesis test?А. 38В. 10С. 20D. 67ОЕ. 53OF.

A data set includes data from 500 random tornadoes. The display from technology available below results from using the tornado lengths (miles) to test the claim that the mean tornado length is greater than 2.7 miles. Use a 0.05 significance level. Use the display to identify the null and alternative hypotheses, test statistic, and P-value. State the final conclusion that addresses the original claim.
