The average life expectancy of tires produced by Whitney Tire Company has been 40,000 miles. Managementbelieves that due to a new production process, the life expectancy of its tires has increased. Which of thefollowing procedure would be the most direct way to determine the validity of this belief?OA hypothesis test in which the alternative hypothesis is that the mean life expectancy of the tires is<40,000.A hypothesis test in which the alternative hypothesis is that the mean life expectancy of the tires is>40,000.A confidence interval for the average life expectancy of the tires.A confidence interval for the average number of the tires produced by Whitney Tire Company.

In this case, the average life expectancy of tires produced by the company has been 40,000 miles.

Answered: The average life expectancy of tires…

Two popular brands of tires for tractor-trailers are the Puma and the Eternal. Salma is a buyer for a major shipping company and wants to determine if there is any difference between the two brands of tire in the mean distance (in thousands of km) driven on them before they need to be replaced. In the company's testing lab, Salma tests a random sample of 14 Puma tires and a random sample of 15 Eternal tires. (These samples are chosen independently.) For the Puma tires, the sample mean distance (in thousands of km) until they would need to be replaced is 54.71 with a sample variance of 5.95. For the Eternal tires, the sample mean distance (in km) until they would need to be replaced is 50.21 with a sample variance of 37.75. Assume that the two populations of distances driven are approximately normally distributed. Can Salma conclude, at the 0.05 level of significance, that there is a difference between the population mean of the distances (in thousands of km) driven on Puma tires before…
In a certain suburb, the mean house price in 2009 was $ 225,000. A real estate agent believes that the mean house price in that suburb has increased since 2009. Please state the null and alternative hypothesis.
A personality test has a subsection designed to assess the "honesty" of the test-taker. Suppose that you're interested in the mean score, 4, on this subsection among the general population. You decide that you'll use the mean of a random sample of scores on this subsection to estimate L. What is the minimum sample size needed in order for you to be 90% confident that your estimate is within 5 of u? Use the value 21 for the population standard deviation of scores on this subsection. Carry your intermediate computations to at least three decimal places. Write your answer as a whole number (and make sure that it is the minimum whole number that satisfies the requirements). (If necessary, consult a list of formulas.) ?
A group of transfer bound students wondered if they will spend the same mean amount on texts and supplies each year at their four-year university as they have at their community college. They conducted a random survey of 54 students at their community college and 66 students at their local four-year university. The sample means were $947 and $1,011, respectively. The population standard deviations are known to be $254 and $87, respectively. You are to conduct a hypothesis test to determine if the means are statistically the same using 5% as alpha What is the computed test statistic?
Professor Nord stated that the mean score on the final exam from all the years he has been teaching is a 79%. Colby was in his most recent class, and his class’s mean score on the final exam was 82%. Colby decided to run a hypothesis test to determine if the mean score of his class was significantly greater than the mean score of the population. α = .01. What is the mean score of the population? What is the mean score of the sample? Is this test one-tailed or two-tailed? Why?
You run a publishing company and you are assessing your proofreaders. You hope that they can proofread an average of 1000 words per hour, an industry benchmark, If they average fewer than 1000 words per hour you will need to reconfigure the staffing. You test the proofreading times of a sample of 100 of the proofreaders and find the sample average words per hour is = whether the population mean words per hour is greater than 1000 with a 95% confidence level. The z-critical value for this test is Z = Zo.05 975 and the sample standard deviation is s = 600. Test 1.645. Show all your steps clearly and illustrate your answer with a graph. %3D
Fertilizer: A new type of fertilizer is being tested on a plot of land in an orange grove, to see whether it increases the amount of fruit produced. The mean number of pounds of fruit on this plot of land with the old fertilizer was 381 pounds. Agriculture scientists believe that the new fertilizer may increase the yield. State the appropriate null and alternate hypotheses. Answer the following question.
Your medical research team is investigating the mean cost of a 30-day supply of a certain heart medication. A pharmaceutical company thinks that the mean cost is less than $53.

Last year the mean cost for a one-bedroom rental in a certain city was $1,200 per month. Eli is looking for a one-bedroom apartment and is investigating whether the mean cost is less now than what it was last year. A random sample of apartments had a sample mean of $1,180 per month. Assuming all conditions for inference are met, Eli will conduct a hypothesis test as part of his investigation. Which of the following is the correct set of hypotheses? Ho: mean = 1200 Ha: mean >1200 Ho: mean = 1200 Ha: mean #1200 Ho: mean = 1200 Ha: mean <1200
Describe a study in which you can use both nonparametric and parametric statistics. A researcher has participants expecting to receive either painful or mild electrical shocks during a study wait in a quarter-full waiting room with other participants. He then measures whether they choose to sit next to other participants or if they sit far away on their own. What is the best test to run for this study and why?
For the given scenario, determine the type of error that was made if any.(begin by determining the null and alternative hypothesis). A new whitening toothpaste advertises for shades as the mean number of shades the toothpaste whitens your teeth. One user claims that the mean number of shades the toothpaste whitens your teeth is different from four shades. The user conducts a hypothesis test and fails to reject the null hypothesis. Assume that in reality, the mean number of shades the two piece white is your teeth is for shade. Was an error made? If so, what type? A, B, C? A.Yes; type 2 error B.Yes; type 1 error C.No; correct decision
A consumer advocacy group is doing a large study on car rental practices. Among other things, the consumer group would like to do a statistical test regarding the mean monthly mileage, µ, of car rented in the U.S. this year. The consumer group has reason to believe that the mean monthly mileage of cars rented in the U.S. this year is different from last year’s mean, which was 2700 miles. The group plans to do a statistical test regarding the value of µ. It chooses a random sample of monthly mileages and computes the mean of the sample to be 2565 miles and the standard deviation to be 800 miles. What are the null hypothesis (H0) and the alternative hypothesis (H1) that should be used for the test? H0: µ is ____ __? __ H1: µ is ____ __ ? ___ In the context of this test, what is a Type II error? A Type II error is ?________ ___ the hypothesis that µ is ? _____ ? when, in fact, µ is ? ____ Suppose that the group decided to reject the null…
