Question

According to a recent study annual per capita consumption of milk in the United States is 22.6 gallons. Being from the Midwest, you believe milk consumption is higher there and wish to test your hypothesis. A sample of 14 individuals from the Midwestern town of Webster City was selected and then each person's milk consumption was entered into the Microsoft Excel Online file below. Use the data to set up your spreadsheet and test your hypothesis. Gallons of Milk 29.6 23.84 25.25 21 17.52 19.61 19.83 26.18 34.97 30 28.59 20.57 26.94 27.24 a. Develop a hypothesis test that can be used to determine whether the mean annual consumption in Webster City is higher than the national mean. b. What is a point estimate of the difference between mean annual consumption in Webster City and the national mean? c. At a=.05, test for a significant difference. What is your conclusion?

Answer #1

= 25.08

s = 4.94

a) H_{0}:
= 22.6

H_{1}:
> 22.6

b) - = 25.08 - 22.6 = 2.48

c) The test statistic t = ( - )/(s/)

= (25.08 - 22.6)/(4.94/)

= 1.878

At
= 0.05, the critical value is t_{0.95, 13} = 1.771

As the test statistic value is greater than the critical value (1.878 > 1.771), we should reject the null hypothesis.

So there is sufficient evidence to support the claim that the mean annual consumption in Webster city is higher than the national mean.

Suppose U.S. consumers 21 years and older consumed 26.4 gallons
of beer and cider per person during 2017. A distributor in
Milwaukee believes that beer and cider consumption are higher in
that city. A sample of consumers 21 years and older in Milwaukee
will be taken, and the sample mean 2017 beer and cider consumption
will be used to test the following null and alternative
hypotheses:
H0: μ ≤ 26.4
Ha: μ > 26.4
(a) Assume the sample data led...

Based on information from the Federal Highway Administration web
site, the average annual miles driven per vehicle in the United
States is 13.5 thousand miles. Assume σ ≈ 650 miles. Suppose that a
random sample of 36 vehicles owned by residents of Chicago showed
that the average mileage driven last year was 13.2 thousand miles.
Would this indicate that the average miles driven per vehicle in
Chicago is different from (higher or lower than) the national
average? Use a 0.05...
