1. Hypothesis testing: A local dog rescue organization claims that it rescues, on average μ = 55 dogs per month, with a = 4 dogs. You think it is less, and you check the last 4 months. On average, the rescue has a sample mean of x = 51 dogs. Set up a hypothesis test that the mean number of dogs rescued is less than 55. Use a = .05. Follow the steps below to help you make a decision. (Assume that the number of dogs rescued per month is normally distributed) What is the null hypothesis? Ho a. b. What is the alternative hypothesis? H₁ 3. Tc. Is this test left tailed, right tailed, or two tailed? d. What is your level of significance? e. Find the z-value of your statistic 1 ordered pairs. Let the x-axis represent the hours f. Find the p-value of your sample statistic. udents' final exam grade. g. Do you reject the null hypothesis, or do you fail the reject the null hypothesis? h. Write a one sentence summary describing your results.
