A population of values has a normal distribution with u draw a random sample of size n = 173. 54.5 and o 93.1. You intend to Find P8, which is the mean separating the bottom 8% means from the top 92% means. P8 (for sample means) = Enter your answers as numbers accurate to 1 decimal place. Answers obtained using exact z- scores or z-scores rounded to 3 decimal places are accepted.

Assume the samples are random and independent, the populations are nomally distributed, and the population variances are equal. The table available below shows the prices (in dollars) for a sample of automobile batteries. The prices are classified according to battery type. At a = 0.10, is there enough evidence conclude that at least one mean battery price is different from the others? Complete parts (a) through (e) below. E Click the icon to view the battery cost data.

A population of values has a normal distribution with 45.2 and a 67.7. You intend to draw a random sample of size n = 108. Please answer the following questions, and show your answers to 1 decimal place. Find the value separating the bottom 35% values from the top 65% values. Find the sample mean separating the bottpm 35% sample means from the top 65% sample means.
To build a 95% CI for the mean of a population, you take a random sample and find these values: 18.4 19.8 17 18.6 23 21.7 18.9 14.3 17.6 21.2 21.4 23.4 20 20.7 15.2 21.9 21 What is the CI? Enter like this: (min,max) Be sure to use the parentheses or you will be marked wrong. Keep at least 3 decimals in all intermediate steps, and round your answer to two decimals. Submit Question
Does Hypnotism Relieve Pain? The table shows the pain levels of patients before and after hypnotism. Pain level is measured on a cm scale. Assume that the two samples are randomly selected. At the 0.05 significance level, test the claim that the mean difference has increased after hypnotism.(Be sure to subtract in the same direction).

USE 3 DECIMAL A producer claims that his potato chips weight has a normal distribution at least 150 grams. The manager tries to test day shift production weight is heavier that night shift. Because of the complaints of the customers, quality control department select randomly 19 bags from the day shift and find the mean as 146 grams and variance 9 grams and randomly selected 21 bags from the night shift and find the mean as 148 grams and variance 8 grams. If manager want to test the claim as night shift mean weight of the product is greater than that of day shift at 1% level of significance. Calculate the test statistics. (H1: m night shift > m day shift).
The height of women ages 20-29 is normally distributed, with a mean of 63.8 inches. Assume o = 2.8 inches. Are you more likely to randomly select 1 woman with a height less than 65.2 inches or are you more likely to select a sample of 23 women with a mean height less than 65.2 inches? Explain. Click the icon to view page 1 of the standard normal table. Click the icon to view page 2 of the standard normal table.

The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 24.2 for a sample of size 26 and standard deviation 21.8. Estimate how much the drug will lower a typical patient's systolic blood pressure (using a 90% confidence level). Assume the data is from a normally distributed population. Enter your answer as a tri-linear inequality accurate to three decimal places. < μ <
