Answer #1

let us consider

Ho =  the average age of male patients the same as  the average age of female patients.

H1 =   the average age of male patients the different then the average age of female patients

Male Female
x bar 44.8 45
S 1 13.3
n 143 109

Standard Error of the Difference (se) =

====1.2766

using t test

t = =   =   -0.1567

P-Value = 0.8758

The distribution of blood cholesterol level in the population of all male patients 20–34 years of age tested in a large hospital over a 10-year period is close to Normal with standard deviation σ = 48 mg/dL (milligrams per deciliter). At your clinic, you measure the blood cholesterol of 14 male patients in that age range. The mean level for these 14 patients is x̄ = 180 mg/dL. Assume that σ is the same as in the general male hospital...

A medical researcher wants to determine if the average hospital stay of patients that undergo a certain procedure is greater than 9.1 days. The hypotheses for this scenario are as follows: Null Hypothesis: μ ≤ 9.1, Alternative Hypothesis: μ > 9.1. If the researcher takes a random sample of patients and calculates a p-value of 0.2003 based on the data, what is the appropriate conclusion? Conclude at the 5% level of significance. Question 5 options: 1) The true average hospital...
