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?
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…
Determine the critical values that would be used in testing each of the following null hypotheses using the classical approach. (Give your answers correct to three decimal places.) (a) Ho: p = 0 vs. Ha: p ≠ 0, with n = 18 and a = 0.05 (smaller value) (larger value)(b) Ho: p = 0 vs. Ha: p > 0, with n = 32 and ? = 0.01 (c) Ho: p = 0 vs. Ha: p < 0, with n = 16 and ? = 0.05
A test of hypothesis has the following details: H0: µ = 50 vs Ha: µ < 50, n = 64, σ = 8, α = 0.04, x¯ = 47, and σ is What is the critical value for this test? (Hint: You will need to use R to calculate the solution to this question). (a) CV = −1.750686 (b) CV = 1.554774 (c) CV = 1.750686 (d) CV = −1.554774
If the critical t is ±1.796 and the obtained t is -2.09, what decision would you make regarding the null hypothesis?
The effectiveness of a new bug repellent is tested on 1616 subjects for a 10 hour period. (Assume normally distributed population.) Based on the number and location of the bug bites, the percentage of surface area exposed protected from bites was calculated for each of the subjects. The results were as follows: ?⎯⎯⎯=92x¯=92, ?=13 s=13 The new repellent is considered effective if it provides a percent repellency of at least 9090. Using ?=0.05α=0.05, construct a hypothesis test with null hypothesis ?≤90μ≤90 and alternative hypothesis ?>90μ>90 to determine whether the mean repellency of the new bug repellent is greater than 9090 by computing the following: (a) the degree of freedom (b) the test statistic The final conclusion is A. There is not sufficient evidence to reject the null hypothesis that ?≤90μ≤90. Our results do not provide enough evidence that the new bug repellent is effective. B. We can reject the null hypothesis that ?≤90μ≤90. Our results indicate that…

Beverage Sample Size Sample Mean Sample SD Strawberry Drink 10 535 24 Cola 10 559 15 Does the data suggest that the extra carbonation of cola results in a higher average compression strength? Base your answer on a P-value. (Use ? = 0.05.) State the relevant hypotheses. (Use ?1 for the strawberry drink and ?2 for the cola.)
