In the tt-test of significance for the hypotheses H0:μ=11 and Ha:μ<11, the value of the test statistic was found to be t = 1.205 using a sample of size 18. Estimate the upper bound for the P-value associated with this test. That is, fill in the blank P <P< _____. Please show work!
Consider the hypotheses shown below. Given that x=113, σ=27, n=42, α=0.10, complete parts a through c below. H0: μ=120 HA: μ≠120 a. State the decision rule in terms of the critical value(s) of the test statistic. Choose the correct answer in parenthesis. Reject the null hypothesis if the calculated value of the test statistic, (z, t) is (not contained within, not contained within, less than, equal to or greater than) the critical value(s), ___??___. Otherwise, do not reject the null hypothesis. (Round to two decimal places as needed. Use a comma to separate answers as needed.) b. State the calculated value of the test statistic. ***Hint: The test statistic for a hypothesis test of the population mean (when σ is known) can be calculated using technology or the formula shown below, where z is the z-test statistic, x is the sample mean, σ is the standard deviation of the population, n is the sample size, and μ is the mean of the sampling distribution, which is assumed…
A company specializes in producing bunkers located in places with extremely cold climates under 0°C. A prototype for a new bunker design using different structure design and materials was tested to have the following average interior temperatures: 23.01, 22.22, 22.04, 22.62, and 22.59. Test that the average interior temperature is equal to 22.5 °C using α = 0.05. a.What are the hypothesis statements?
