Per the Barron's report the average weeks unemployed is 21.5 (population mean) with a population standard deviation of 5 weeks and a sample of 55. In the next five questions we will be calculating the probability that the sample of 55 will provide a mean within 1 week of the population mean. What is the probability to 4 decimals for (x<22.5)? Use the rounded standard error of the mean in calculations.

(c) After you obtain your ten observations, you compute the mean number of hours of sleep. Is this a statistic or a parameter? Why?
O of 5 A random sample of 77 eighth grade students' scores on a national mathematics assessment test has a mean score of 273. This test result prompts a state school administrator to declare that the mean score for the state's eighth graders on this exam is more than 270. Assume that the population standard deviation is 35. At a = 0.09, is there enough evidence to support the administrator's claim? Complete parts (a) through (e). %3D (a) Write the claim mathematically and identify Ho and Ha. Choose the correct answer below. O A. Ho: μ2 270 (claim) Ha: В. Но: С. Но: u = 270 Ha: H = 270 (claim) Ha: H> 270 μ> 270 (claim) H 270 (claim) O E.

A sample of size 126 will be drawn from a population with mean 26 and standard deviation 3. Use the TI-84 calculator. Part 1 of 2 Find the probability that x will be between 25 and 27. Round the answer to four decimal places. The probability that x will be between 25 and 27 is Part 2 of 2 th Find the 55 percentile of X. Round the answer to two decimal places. The 55th percentile is
A simple random sample of size n=30 is drawn from a population that is normally distributed. The sample mean is found to be 25 and the sample standard deviation is found to be 2. The claim is the population mean is different from 26 at 5% significance. Calculate the value of the test statistics? Round to 2 decimal places.
A medical researcher wants to investigate the amount of time it takes for patients’ headache pain to be relieved after taking a new prescription painkiller. She plans to use statistical methods to estimate the mean of the population of relief times. She believes that the population is normally distributed with population standard deviation σ = 12 minutes. How large a sample should she take to estimate the mean time to within 2.5 minutes with 95% confidence?A medical researcher wants to investigate the amount of time it takes for patients’ headache pain to be relieved after taking a new prescription painkiller.

A study of college football games shows that the number of holding penalties assessed has a mean of 2.2 penalties per game and a standard deviation of 0.9 penalties per game. What is the probability that, for a sample of 40 college games to be played next week, the mean number of holding penalties will be 2.25 penalties per game or less? Carry intermediate computations to at least 4 decimal places. Round answer to at least 3 decimal places.
