Listed in the data table are 10 scores for a random sample of subjects with medium load levels in their blood. Also listed are statistics from a study done of IQ scores for a random sample of subjects with high lead levels. Assume that the two samples are independent simple random samples selected from normally distributed populations. Do not assume that the population standard deviations are equal. Complete parts (a) and (b) below. Use a 0.05 significance level for both...

Decide whether the normal sampling distribution can be used. It can be used, test the dam about the population proportion p at the given level of significance a using the given sample statistics Claim p 0.26 0.05, Sample statistics: p=0.22, n = 100 Can the normal sampling distribution be used? O A No, because ng is less than 5. OB. Yes, because both np and ng are greater than or equal to 5. OC. No, because np is less than...

A data set includes data from student evaluations of courses. The summary statistics are nequals 91, x overbar equals4.17, sequals 0.69. Use a 0.10 significance level to test the claim that the population of student course evaluations has a mean equal to 4.25 . Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. What are the null and alternative hypotheses? A....

The owner of a local soccer team claims that average attendance at games is more than 200. Assuming that a hypothesis test of the claim has been conducted and that the conclusion is to fail to reject the null hypothesis, state the conclusion in non-technical terms. A) There is sufficient evidence to support the claim that the mean attendance is at most 200. B) There is not sufficient evidence to support the claim that the mean attendance is at most...
