test the claim that the mean GPA of night students is significantly different than 3.4 at the 0.1 significance level. the null and alternative hypothesis would be: The test is:? Based on the sample of 20 people, the sample mean GPA was 3.35 with a standard deviation of 0.04. The test statistic is: ? (to 2 decimals) The P-value is: ? (To 2 decimals) Based on this we: Fail to reject the null hypothesis or we reject the null hypothesis
Data previously obtained, lists full IQ scores from a random sample of subjects with low lead levels in their blood and another random sample of subjects with high lead levels in their blood. The statistics are listed below. Use a 0.05 significance level to test the claim that the mean IQ score of people with low blood lead levels is higher than the mean IQ score of people with high blood lead levels. Low Blood Lead Level High Blood Lead Level n1 = 78 n2 = 21 X1 = 92.88462 X2 = 86.90476 S1 = 15.34451 S2 = 8.988352 State the claim: State the claim in symbols Null and Alternative hypotheses: What type tail test?

Medical researchers interested in determining the relative effectiveness of two different drug treatments on people with a chronic mental illness established two independent test groups. The first group consisted of 13 people with the illness, and the second group consisted of 14 people with the illness. The first group received treatment 1 and had a mean time until remission of 178 days, with a standard deviation of 5 days. The second group received treatment 2 and had a mean time until remission of 172 days, with a standard deviation of 8 days. Assume that the populations of times until remission for each of the two treatments are normally distributed with equal variance. Can we conclude, at the 0.05 level of significance, that the mean number of days before remission after treatment 1, u1, is greater than the mean number of days before remission after treatment 2, µ,?
