The mean length of lumber is supposed to be 8.5 feet. A builder wants to check whether the shipment of lumber she receives has the correct length, so she conducts a hypothesis test. She measures 61 randomly selected pieces of lumber and finds they have a mean of 8.3 feet and standard deviation of 0.75 feet. With the help of Mathematics & R Studio: Conduct a hypothesis test to see whether she is justified to believe that the average is shorter than 8.5 feet?
TASK YOUR FINAL Instruction: State the null hypothesis and the alternative hypothesis in (a) words and in (b symbols for each of the following. Write your answer on the answer sheet provided. 1. A librarian of a school claims that all their Grade 8 students read an average of 18 storybooks a month with a standard deviation of 2 books.

A golf analyst claims that the standard deviation of the 18-hole scores for a golfer is less than 2.9 strokes. State H0 and Ha in words and in symbols. Then determine whether the hypothesis test for this claim is left-tailed, right-tailed, or two-tailed. Explain your reasoning. State the null hypothesis in words and in symbols. Choose the correct answer below. A. The null hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer is at least 2.9 strokes." The null hypothesis is expressed symbolically as, "H0: σ≥2.9." B. The null hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer is not 2.9 strokes." The null hypothesis is expressed symbolically as, "H0: σ≠2.9." C. The null hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer is less than 2.9 strokes." The null hypothesis is expressed symbolically as, "H0: σ<2.9." D. The null hypothesis expressed in…

. nonzerorands expects 3 arguments The average American consumes 100 liters of alcohol per year. Does the average college student consume a different amount of alcohol per year? A researcher surveyed 15 randomly selected college students and found that they averaged 86 liters of alcohol consumed per year with a standard deviation of 16 liters. What can be concluded at the the a = 0.05 level of significance? a. For this study, we should use t-test for a population mean b. The null and alternative hypotheses would be: Ho: μν H₁: 100 100 E -3.389 (please show your answer to 3 decimal places.) (Please show your answer to 4 decimal places.) c. The test statistic t d. The p-value = e. The p-value is > ✓ a f. Based on this, we should fail to reject g. Thus, the final conclusion is that ... the null hypothesis. O The data suggest the populaton mean is significantly different from 100 at a = 0.05, so there is statistically significant evidence to conclude that the population mean amount of…

The cost of a car is $30k at Joe's Garage. You cant to see if the cost is lower at Pete's Garage. To test, you collect data from 64 buyers who recently bought cars. The average of your sample is $29,760, with a sample standard deviation of $7,450. Using this data to perform the hypothesis test with H0: u=30,000 vs H0:u<30,000, what is the p-value of this test, and what is the conclusion of this test at the a=.05 level?
