We want to conduct a hypothesis test of the claim that the population mean score on a nationwide examination in anthropology is different from 505. So, we choose a random sample of exam scores. The sample has a mean of 492 and a standard deviation of 78. For each of the following sampling scenarios, choose an appropriate test statistic for our hypothesis test on the population mean. Then calculate that statistic. Round your answers to two decimal places. (a) The sample has size 10, and it is from a normally distributed population with an unknown standard deviation. O z = O It is unclear which test statistic to use. (b) The sample has size 105, and it is from a non-normally distributed population with a known standard deviation of 76. O z=] Ot=] O It is unclear which test statistic to use.

You want to obtain a sample to estimate a population mean. Based on previous evidence, you believe the population standard deviation is approximately σ=21.4. You would like to be 98% confident that your estimate is within 5 of the true population mean. How large of a sample size is required?
See pictures for question D and E and (A, B and Cand was submitted on a different question. According to a report done by S & J Power, the mean lifetime of the light bulbs it manufactures is 44 months. A researcher for a consumer advocate group tests this by selecting 16 bulbs at random. For the bulbs in the sample, the mean lifetime is 47 months. It is known that the population standard deviation of the lifetimes is 5 months. Assume that the population is normally distributed. Can we conclude, at the 0.10 level of significance, that the population mean lifetime, μ, of light bulbs made by this manufacturer differs from 44 months? Perform a two-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places, and round your responses as specified below.
For the following dataset, you are interested to determine the "spread" of the data. Would you employ calculations for the sample standard deviation, or population standard deviation for this dataset: The weight of each apple in a shipment of 1000 apples.
Task I: Two teams (A and B) at Ferrari company are trying to develop the best California T for this project. Your supervisor asked you to compare two different samples of each team. You need to examine a sample of 50 cars from each group and measure their maximum speed. Use the results shown in table 1 below to determine the following: What is the mean, mode, median, and standard deviation of maximum speeds for each group of cars? Divide each data group into four categories and create the frequency table for each category. Calculate the mean and standard deviation from the frequency tables and compare to results found in part a. Present the data as a histogram. Present the data as frequency polygon Table 1 Team A Team B Maximum Speed (mph) 185.3220 187.8136 185.1793 184.4689 187.0496 186.9742 184.2262 189.5322 185.4633 188.7326 185.6820 190.9942 183.4812 188.9213 185.6793 186.0114 186.6068 191.8264…
Use z scores to compare the given values. The tallest living man at one time had a height of 238 cm. The shortest living man at that time had a height of 142.4 cm. Heights of men at that time had a mean of 175.45 cm and a standard deviation of 5.59 cm. Which of these two men had the height that was more extreme? ... Since the z score for the tallest man is z = 0 and the z score for the shortest man is z = the man had the height that was Im- more extreme. (Round to two decimal places.) shortest tallest

Is the following statements correct or incorrect: Suppose that a random vector Y' = (Y1, Y2, Y3) has multi-normal distribution with mean vector u and variance-covariance matrix £ given by and Σ 흑 0 1 respectively. CH), Then the distribution of Z = Y is N 1
A standardized exam's scores are normally distributed. In a recent year, the mean test score was 1458 and the standard deviation was 312. The test scores of four students selected at random are 1860, 1220, 2150, and 1340. Find the z-scores that correspond to each value and determine whether any of the values are unusual. The z-score for 1860 is (Round to two decimal plaes as needed.)
The first experiment I created 200 samples with 10 students in each and took each sample's mean. The mean of this distribution was about 10.7 miles with a standard deviation of 3.7 miles. (See video) Next I did 200 samples with 20 students each, then I did 200 samples with 50 students each and finally I did 200 samples with 100 students each. Watch the following video and answer the following questions about the sampling distributions being created. 1) For the samples with 100 students each, when the sampling is complete, what will the mean be close to or equal to? 2) For the samples with 100 students each, when the sampling is complete, will the standard deviation be smaller than the standard deviation for the samples with 50 students each? 3) What is the mean of the population of students that I am randomly sampling from? 4) What is the name of the important theorem that I am demonstrating right now.?
