Question

I believe that 67% of US households own a pet. A survey of 50 employees out of 120 employees of PRO Systems showed that 49 owned a pet. Test this hypothesis at the .15 significance level. Assume a random sample. Include the null and alternative hypothesis, alpha value, p-value, and a conclusion. Make sure that you use appropriate terminology, specify whether you are using the classical method or the p-value method, and fully explain your solution.

Answer #1

A humane society claims that less than 67% of US households own
a pet. In a random sample of 600 US households, 390 say they own a
pet. Use a 0.01 significance level to test the humane society’s
claim.
a. Hypothesis (steps 1-3):
b. Value of Test Statistic (steps 5-6):
c. P-value (step 6):
d. Decision (steps 4 and 7):
e. Conclusion (step 8):

I believe the proportions of individuals who own an Nintendo
Switch is greater than those that own an Xbox One. A poll showed
that out of 6,000 people, 3,560 out of 6,000 individuals owned a
Nintendo Switch and 2,440 out of 6,000 individuals owned an Xbox
One.
Test this data at a 90% confidence interval.
Make sure that you use appropriate terminology and specify
whether you are using the classical method or the p-value
method.

According to the 2017-2018 U.S. Pet Ownership & Demographics
Sourcebook, 38.4% of US households own a dog. Ms Ferguson believes
the percent of households who own a dog has changed since 2018, so
she polls 90 students and finds that 39 students own a dog. Test
Ms. Ferguson’s claim at the α = 0.05 significance level. Regardless
of which method you use, sketch a graph showing the critical region
and where the test statistic falls - inside or outside the...
