3) A power company wished to test the null hypothesis that the mean time for processing rebates was equal to 3.5 minutes, against the alternative that it was greater. A sample of mean time of 3.8 minutes was obtained from a sample of n - 40 rebate applications. State hypotheses, compute test statistic, P-value, and state if the null hypothesis would be rejected at -.01 (Assume the population standard deviation is -1.2 minutes) H : - H: : P-value ;...

Question 5 of 6 (1 point) View problem in a pop-up 8.2 Section Exercise 22 Ten years ago, the average acreage of farms in a certain geographic region was 65 acres. The standard deviation of the population was 7 acres. A recent study consisting of 26 farms showed that the average was 62.5 acres per farm. Test the claim, at 0.10, that the average has not changed by finding theP-value for the test. Assume o has not changed and the...

question 2-c and 2-d
2 .c) Test the given hypothesis. Assume that the population is normally distributed and that the sample has been randomly selected. A manufacturer uses a new production method to produce steel rods. A random sample of 17 steel rods resulted in lengths with a standard deviation of 4.7 cm. At the 0.10 significance level, test the claim that the new production method has lengths with a standard deviation different from 3.5 cm, which was the standard...

Q2. Hypothesis Testing with a Z test (14 points total) A research institute examined the number of smart phones and tablets connected to the internet in American households and reported a mean (μ) of 5 devices per household and a standard deviation (σ) of 1.5 devices. But I wonder if the statistics in my neighborhood, Chandler, would be different from the national average. To test this idea, I randomly picked 16 friends of mine living in Chandler and asked them...

For all Hypothesis test problems, please do the following; following the steps as discussed in class: 1. Is the data discrete or continuous? 2. List the assumptions 3. State the null and alternate hypothesis. 4. Write down the proper test statistic, Show all calculations, i.e. impute the numbers. Set up Decision rules. Show the critical value. Reject or Fail to reject. 5. State your conclusions. Problem 10-29 According to this table, 711 survived. Class ...

QUESTION 3 (a) Consider the following hypothesis: ?0 ∶ ? ≤ 12.6 ?1 ∶ ? > 12.6 A sample of 25 measurements yields a sample mean of 13.4. Assuming that the sample is drawn from a normal distribution with a known population standard deviation of 3.2. (i) Use Z-test to determine the conclusion if ? = 0.10. (ii) Use p-value test to determine the conclusion if ? = 0.10. [15 marks] (b) A perfume factory wishes to ensure that an...
