A sample mean, sample size, and population standard deviation are given. Use the one-mean z-test to perform the required hypothesis test about the mean, μ, of the population from which the sample was drawn. x-bar = 25, n = 60, σ = 1.5, H0: μ = 22; Ha: μ ≠ 22, α = 0.05
a. Reject H0 if z < -1.96 or z > 1.96; z = 15.49; therefore reject H0 and conclude that μ ≠ 22.
b. Reject H0 if -1.96 < z < 1.96; z = 15.49; therefore do not reject H0.
c. The data do not provide sufficient evidence to support Ha: μ ≠ 22.
d. Reject H0 if z < -1.645 or z > 1.645; z = 15.49; therefore reject H0 and conclude that μ ≠ 22.
e. Reject H0 if -1.645 < z < 1.645; z = 15.49; therefore do not reject H0.
f. The data do not provide sufficient evidence to support Ha: μ ≠ 22.

Asap for seven months an ice creams vendor collects data showing the number of cones sold a day (c) and the degrees above 70 degrees f the vendor finds that there is a positive linear association between c and t that is the best modeled by this equation c=3.7t+98 which statement is true? the model predicts that the average number of cones sold in a day is 3.7 the model predicts that the average number of cones sold i a day is 98 a model predicts that for each additional degree that the high temperature is above 70 degres f the total of number of cones sold increases by 3.7 the model predicts for each additional degree that the high temperature is above 70 degrees f the total number of cones sold increasingly by 98
