Suppose IQ scores were obtained for 20 randomly selected sets of twins. The 20 pairs of measurements yield x=99.69, y=101.15, r=0.903, P-value=0.000, and y=−0.2+1.02x, where x represents the IQ score of the twin born second. Find the best predicted value of y given that the twin born second has an IQ of 108? Use a significance level of 0.05. The best predicted value of Y is?

Listed in the data table are IQ scores for a random sample of subjects with medium lead 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 deviation’s are equal. Use a 0.05 significance level to test the claim that the mean IQ scores for subjects with medium lead levels is higher than the mean for subjects with high lead levels. What is the test statistic What is the P value Construct a confidence interval

A sample of 126 corporate managers and another sample of 168 college professorsproduced mean job-related stress scores of 7.35 for the managers and 6.86 for theprofessors. Suppose that the standard deviations of the stress scores are 1.12 for themanagers and 1.82 for the professors. The null hypothesis is that the mean stress scoresare the same for corporate managers and college professors, while the alternativehypothesis is that the mean stress score for managers is different from the mean stressscore for professors. Should you reject or fail to reject the null hypothesis in this test?
A random sample of 170 donations at a certain blood bank reveals that 84 were Type A blood. Does this suggest that the actual percentage of Type A donations differs from 45%, of the population having Type A blood? A. State H0 and Ha B. Test the hypothesis using the P-Value approach at a significance level of 3%, and express your decision. C Based on the given data, determine the extreme value without rejecting the H0.
Is the proportion of wildfires caused by humans in the south lower than the proportion of wildfires caused by humans in the west? 360 of the 501 randomly selected wildfires looked at in the south were caused by humans while 435 of the 588 randomly selected wildfires looked at the west were caused by humans. What can be concluded at the = 0.10 level of significance? For this study, we should use Select an answer t-test for the difference between two dependent population means z-test for the difference between two population proportions t-test for a population mean t-test for the difference between two independent population means z-test for a population proportion The null and alternative hypotheses would be: Select an answer μ1 p1 Select an answer < ≠ > = Select an answer μ2 p2 (please enter a decimal) Select an answer μ1 p1 Select an answer > ≠ < = Select an answer p2 μ2 (Please enter a decimal) The test statistic ? z t = (please show your…
