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.

1.) Part 4?

Check our blood pressure: In a recent studjrr 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? The proportion of women who have blood pressures between 71 and 89 is 0.6453 . {d} Is it unusual for a woman to have a blood pressure lower than 68'? It unusual because me probability of a woman having blood pressure lower man 68 is D. IS Coffee: The National Coffee Association reported that 61% of U.S. adults drink colTee daily. A random sample of 250 U.S. adults is selected. Round your answers to at least four decimal places as needed. (a) Find the mean pa. P The mean u; is -. (b) nd the standard deviation on. P The standard deviation on is 0.0308 . P (c) Find the probability that more than 65% of the sampled adults drink coffee daily. The probability that more than 65% of the sampled adults drink coffee daily is 0.0974 . ([1) nd the probability that the proportion of the sampled adults who drink coffee daily is between 0.59 and 0.68. The probability that the proportion of the sampled adults Who drink coffee daily is between 0.59 and 0.68 is [:J. Blood pressure: High blood pressure has been identied as a risk factor for heart attacks and strokes. The proportion of U.S. adults with high blood pressure is 0.3. A sample of 42 U.S. adults is chosen. Use the TI84 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 (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 0.0169 . A new sample of 81 adults is drawn. Find the probability that more than 39% of the people in this sample have high blood pressure. The probability that more than 39% of the people in this sample have high blood pressure is 0.0386 . Find the probability that the proportion of individuals in the sample of 81 who have high blood pressure is between 0.24 and 0.34. The probability that the proportion of individuals in the sample of 81 who have high blood pressure is between 0.24 and 0.34 is B . Watching TV: In 2012, the General Social Survey asked a sample of 1310 people how much time they spent watching TV each day. The mean number of hours was 2.8 with a standard deviation of 2.6. A sociologist claims that people watch a mean of 3 hours of TV per day. Do the data provide sufcient evidence to conclude that the mean hours of TV watched per day is less than the claim? Use the a: 0.10 level of signicance and the Pvalue method with the "IT84 Plus calculator. (a) State the appropriate null and alternate hypotheses. This hypothesis test is a lefttailed V tESt- {b} Compute the Pvalue. Round the answer to at least four decimal places. Pvalue = (c) Determine whether to reject H0. Reject v the null hypothesis Ho. (d} State a conclusion. less than 3 hours. There (Choose one) 1 enough evidence to conclude that the mean time watching TV is - Good credit: The Fair Isaac Corporation (FICD) credit score is used by banks and other lenders to determine whether someone is a good credit risk. Scores range from 300 to 850, with a score of 720 or more indicating that a person is a very good credit risk. An economist wants to determine whether the mean FICO score is lower than the cutoff of 720. She nds that a random sample of 60 people had a mean FICO score of 695 with a standard deviation of 65. Can the economist conclude that the mean FICD score is less than 720? Use the o. = 0.05 level of signicance and the Pualue method with the TI84 Plus calculator. State the appropriate null and alternate hypotheses. H0: p = 720 H]: [1
