Good evening, I need answers to these questions please. I write fantastic reviews. Also if you need to use your calculator or an excel sheet please use what you need.

Check our blood pressure: In a recent study, the Centers for Disease Control and prevention reported that diastolic blood pressures of adult women in the United States are approximately normally distributed with mean 80.3 and a standard deviation of 9.7. Round the answers to four decimal places. (a) What proporb'on of women have blood pressures lower than 64? The proportion of women who have blood pressures lower than 64 is . {b} What proportion of women have blood pressures between 71 and 89?

A sample of 42 U.S. adults is chosen. Use the "Fl34 Plus Calculator as needed. Round the answer to at least four decimal places. Is it appropriate to use the normal approximation to nd the probability that more than 45% of the people in the sample have high blood pressure? It [E appropriate to use the normal curve, since up = _10 .u w) = Find the probability that more than 45% of the people in this sample have high blood pressure. The probability that more than 45% of the people in this sample have high blood pressure is D. Complete the following sentences. Part 1 of 2 V If X is a binomial random variable and if mp = 10 and n(1-p) > 10, then X is approximately normal with HY = Inp and ov = np (1 - p) Part: 1 / 2 Part 2 of 2 When asked to find P (X 50. If a Type I error is made, what conclusion will be drawn regarding the mean breaking strength? The conclusion will be that the mean breaking strength is greater than V 50. If a Type 11 error is made, what conclusion will be drawn regarding the mean breaking strength? The conclusion will be that the mean breaking strength is 'equal to V l 50. This test uses a onetailed alternative hypothesis. Explain why a onetailed hypothesis is more appropriate than a twotailed hypothesis in this situation. With a onetailed hypothes'w we can conclude that the mean breaking strength is 50. With a twotailed hypothesis, we will not know whether - the mean breaking strength is 50. native hypothesis. Explain Why a 0 equal to not equal to less than bre greater than less than or greater than Sis, W greater than 50.More time on the Internet: A researcher polled a sample of 1066 adults in the year 2010, asking them how many hours per week they spent on the Internet. The sample mean was 9.42 with a standard deviation of 13.65. A second sample of 1059 adults was taken in the year 2012. For this sample, the mean was 10.49 with a standard deviation of 14.45. Assume these are simple _ random samples from populations of adults. Can you conclude that the mean number of hours per week spent on the Internet differs between 2010 and 2012.? Let 1;] denote the mean number of hours spent on the Internet in 2010. Use the u = 0.10 level and the Pvalue method with the \"IT84 calculator. State the appropriate null and alternate hypotheses. This is a twotailed 7 test. Compute the Pvalue. Round the answer to at least four decimal places. hm SAT coaching: A sample of 10 students took a class designed to improve their SAT mat'n scores. Following are their scores before and after the class. Can you conclude that the mean increase in scores is less than 15 points? Let \"I represent the mean score after the class and \"id = H 1.1.2. Use the u = 0.05 level and the Pvalue method with the TI34 Plus calculator.

This isa lefttailed Y tESt- (b) Compute the Pvalue. Round the answer to at least four decimal places. Pvalue = D Is the lottery fair? Power ball is a multistate lottery in which players try to guess the numbers that will turn up in a drawing of numbered balls. One of the balls drawn is the "Powerball." Matching the number drawn on the Powerball increases one's winnings. In a 1'? month period, the Power ball was drawn from a collection of 35 balls numbered 1 through 35. A total of 152 drawings were made. For the purpose of this exercise, we grouped the numbers in to ve categories: 17, 814, and so on. If the lottery is fair, then the winning number is equally likely to occur in any category. Following are the observed frequencies. Test the hypothesis that each of the categories is equally likely. Use the 0.05 level of signicance and the Pvalue method with the 1184 Plus calculator.

A recent study examined the elTects of carbon monoxide exposure on a group of construction workers. The following table presents the numbers of workers who reported various symptoms, along with the shift (morning, evening, or night) that they worked.

Use the u = 0.01 level of signicance and the Pvalue method with the "IT84 Plus calculator. What do you conclude? State the null and alternate hypotheses. H0: The shift and reported symptoms independent. H1: The shift and reported symptoms independent. This hypothesis test is a righttailed 1' test. Find the Pyalue. Round your answer to four decimal places. The Pyalue is D . Foot temperatures: Foot ulcers are a common problem for people with diabetes. Higher skin temperatures on the foot indicate an increased risk of ulcers. In a study performed at the Colorado School of Mines, skin temperatures on both feet were measured, in degrees Fahrenheit, for 8 diabetic patients. The results are presented in the following table.
