Several years ago, the mean height of women 20 years of age or older was 63.7 inches. Suppose that a random sample of 45 women who are 20 years ofage or older today results in a mean height of 64.7 inches.(a) State the appropriate null and alternative hypotheses to assess whether women are taller today.(b) Suppose the P-value for this test is 0.14. Explain what this value represents.(c) Write a conclusion for this hypothesis test assuming an a= 0.05 level of significance......(a) State the appropriate null and alternative hypotheses to assess whether women are taller today.O A.

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…
Suppose that you were interested in investigating the effect of a drug that is to be used in the treatment of patients who have glaucoma in both eyes. A comparison between the mean reduction in eye pressure for this drug and for a standard treatment is desired. Both treatments are applied directly to the eye. (a) Describe a reasonable method of collecting data that would result in paired samples. Gather a number of volunteers who suffer from glaucoma in both eyes. Measure the pressure in each eye of each participant before the treatments begin. For each experimental subject, randomly assign the treatments to each participant. Once the patients have applied the treatments for a fixed time, measure again the pressures in all the eyes, and compare the mean reduction in pressure for the eyes that have received the new treatment with the mean reduction in pressure for those that have received the standard treatment. O Gather a number of volunteers who suffer from glaucoma in both eyes.…
A manufacturer of bolts has a quality control policy that requires it to destroy any bolts that are more than 2 standard deviations from the mean. A sample of 15 bolts were tested and their variance was recorded to be 10. Stating any assumptions you need to make, test, at the 5% level, whether the bolts are meeting the established standard.
A manufacturer must test that his bolts are 4.00 cm long when they come off the assembly line. He must recalibrate his machines if the bolts are too long or too short. After sampling 121 randomly selected bolts off the assembly line, he calculates the sample mean to be 4.21 cm. He knows that the population standard deviation is 0.83 cm. Assuming a level of significance of 0.02, is there sufficient evidence to show that the manufacturer needs to recalibrate the machines? Step 3 of 3: Draw a conclusion and interpret the decision.

I know I am just missing a small piece of it. hypothesist test for single population mean and single population proportion. need to figure out test statistic . and "p" value 2. 20% all college students volunteer their time. is the percentage of college student who are volunteers different for students receiving financial aid? of the 387 randomly selected students who receive financial aid, 58 of them volunteered their time. what can be concluded at the alpha 0.05 level of significance.

A common idea is that people can temporarily postponed death to survive a major holiday or important event. A study found that there were 6907 deaths before Thanksgiving and 5739 deaths after Thanksgiving. Test the claim at the 0.05 significance level that the proportion of deaths in the week before Thanksgiving is less that 0.5. Based on your result, does it appear that peole can temporarily postpone death to survive the Thanksgiving holiday?
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?

We want to estimate the mean distance travelled to work by employees of a large manufacturing firm. Past studies indicate that the variance of these distances is 4.0 km2and that the distances follow a normal distribution. How many employees should be chosen at random and polled if the estimated mean distance is to be within 0.1 km ofthe true mean with a confidence level of 95%?
A coin-operated coffee machine made by BIG Corporation was designed to discharge a mean of 7.1 ounces of coffee per cup. If it dispenses more than that on average, the corporation may lose money, and if it dispenses less, the customers may complain. Believing that the mean amount of coffee dispensed by the machine, µ, is less than 7.1 ounces, BIG plans to do a statistical test of the claim that the machine is working as designed. Technicians gather a random sample of fill amounts and find that the mean of the sample is 6.7 ounces and that the standard deviation is 0.4 ounces. Based on this information, answer the questions below.
In the US, the average one-way commuting time is 26.4 minutes. Is this different in Atlanta? One survey of 35 Atlanta commuters found an average one-way commuting time of 30.7 minutes. (a) The test statistic is 1.1846. What is the meaning of this test statistic? The average error between different sample results and the hypothesized mean is 1.1846.The current sample result is 1.1846 standard errors above the hypothesized mean. The maximum error between different sample results and the hypothesized mean is 1.1846. (b) Based on the test statistic of 1.1846, what is the p-value to test if the average commuting time in Atlanta is different than the rest of the US? (4 decimals.) (c) On the basis of the above p-value, what can be said regarding a 95% confidence interval for the true average commuting time? The interval contain the value 26.4, because this value . (d) Suppose the sample size was increased to 120 Atlanta commuters, with other values remaining the same. How would…
