The mean SAT Score in mathematics is 523. The standard deviation of these scores is 39. A special preparation course claims that the mean SAT score, u, of its graduates is greater than 523. An independent researcher tests this by taking a random sample of 33 students who completed the course; the mean SAT score in mathematics for the sample was 541. Assume that the population is normally distributed. At the 0.01 level of significance, can we conclude that the population mean SAT score for graduates of the course is greater than 523? Assume that the population standard deviation of the scores of course graduates is also 39. Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places, and round your responses as specified below. (If necessary, consult a list of formulas.)

A nationwide job recruiting firm wants to compare the annual incomes for childcare workers in Texas and Virginia. Due to recent trends in the childcare industry, the firm suspects that the mean annual income of childcare workers in Texas is less than the mean annual income of childcare workers in Virginia. To see if this is true, the firm selected a random sample of 10 childcare workers from Texas and an independent random sample of 10 childcare workers from Virginia and asked them to report their mean annual income. The data obtained were as follows. Annual income in dollars Техas 26950, 39167, 36383, 37183, 46661, 39149, 36562, 32419, 21419, 39430 Virginia 33493, 27316, 38616, 42893, 35369, 34236, 30451, 32245, 42865, 32494 Send data to calculator Send data to Excel The population standard deviation for the annual incomes of childcare workers in Texas and in Virginia are estimated as 6100 and 6300, respectively. It is also known that both populations are approximately normally…
Before changes to its management staff, an automobile assembly line operation had a scheduled mean completion time of 14.2 minutes. The standard deviation of completion times was 1.6 minutes. An analyst at the company suspects that, under new management, the mean completion time, µ, is now less than 14.2 minutes. To test this claim, a random sample of 12 completion times under new management was taken by the analyst. The sample had a mean of 13 minutes. Assume that the population is normally distributed. Can we support, at the 0.01 level of significance, the claim that the population mean completion time under new management is less than 14.2 minutes? Assume that the population standard deviation of completion times has not changed under new management. Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places, and round your responses as specified below. (If necessary, consult a list of formulas.)
Question 10: give the conclusion.
More errors For each of the following situations, statewhether a Type I, a Type II, or neither error has been made.a) A test of H0: p = 0.8 vs. HA: p 6 0.8 fails to reject thenull hypothesis. Later it is discovered that p = 0.9.b) A test of H0: p = 0.5 vs. HA: p ≠ 0.5 rejects the nullhypothesis. Later is it discovered that p = 0.65.c) A test of H0: p = 0.7 vs. HA: p 6 0.7 fails to reject thenull hypothesis. Later is it discovered that p = 0.6.
Which of the following statements about hypothesis testing are true? There may be more than one correct statement; check all that are true. a) The most common test in one sample problems is of the null hypothesis: Ho : μ = σ b) If the null hypothesis is true, we cannot make a type I error. c) The most important contribution of hypothesis testing is that it allows us to use known values of parameters to estimate unknown values of their statistical estimators. d) If a null hypothesis is rejected at the 0.05 significance level, it would also be rejected at the 0.10 significance level.
