Suppose you want to estimate the mean bowling score for all participants in a large bowling league. The stemplot summarizes the distribution of bowling scores for a random sample of 18 bowlers in the league. 2410 24 668 25 001124 25 55688 26 01 26 5 Key: 26 | 5 = A bowler that scored 265. Is the Normal/Large Sample condition met? Explain. Yes! Although the sample size is small, the graph of the sample data shows no strong skewness or outliers. No, the sample size is small and the graph of the sample data is strongly skewed to the right with at least one high outlier. No, the sample size is small, n = 18 < 30. There is not enough information provided to determine if the Normal/Large Sample condition is met. Yes, the data come from a normally distributed population.
The average retirement age in America is 64 years old. Brianna thinks that yoga teachers owners retire at age that is younger than average. We want to test Brianna's claim at the 0.09 level of significance. The data below shows the results of a survey of yoga teachers about the age where they retired.

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).

6.3.10 Question Help ▼ Three randomly selected households are surveyed. The numbers of people in the households are 1, 4, and 10. Assume that samples of size n =2 are randomly selected with replacement from the population of 1, 4, and 10. Construct a probability distribution table that describes the sampling distribution of the proportion of odd numbers when samples of sizes n = 2 are randomly selected. Does the mean of the sample proportions equal the proportion of odd numbers in the population? Do the sample proportions targe the value of the population proportion? Does the sample proportion make a good estimator of the population proportion? Listed below are the nine possible samples. 1,1 1,4 1,10 4,1 4,4 4,10 10,1 10,4 10,10 2 Construct the probability distribution table. Sample Proportion Probability (Type an integer or fraction.)
