KSystolic blood pressure levels above 120 mm Hg are considered to be high. For the 100 systolic blood pressure levelslisted in the accompanying data set, the mean is 120.46000 mm Hg and the standard deviation is 15.31318 mm Hg.Assume that a simple random sample has been selected. Use a 0.10 significance level to test the claim that the sampleis from a population with a mean greater than 120 mm Hg.Click the icon to view the data set of systolic blood pressure levels.Identify the null and alternative hypotheses.=μ120Ho:H₁: μ > 120(Type integers or decimals.

The U.S. Center for Disease Control reports that in year 1900, the mean life expectancy is 47.6 years for whites and 33 years for nonwhites. (Click here for reference data) Suppose a survey of randomly selected death records for white and nonwhite people born in 1900 from a certain county is conducted. Of the 110 whites surveyed, the mean life span was 48.2 years with a standard deviation of 11.2 years and of the 95 nonwhites, the mean life span was 39.3 years with a standard deviation of 16 years. Conduct a hypothesis test at the 0.05 level of significance to determine whether there was no difference in mean life spans in the county for whites and nonwhites in year 1900. Preliminary: Is it safe to assume thatnw≤5% of all white people born in 1900 andnnw≤5% of all nonwhite people born in 1900? No Yes Is nw≥30 and nnw≥30 ?
