A sample of blood pressure measurements is taken from a data set and those values (mm Hg) are listed below The values are matched so that subjects each have systulic and diastolic measurements, Find the mean and median for each of the two samples and then compare the two sets of results Are the measures of center the best statistics to use With these data?

(Type integers or decimals rounded to one decimal place as needed ) Waiting times (in minutes) of customers in a bank where all customers enter a single waiting line and a bank where customers wait in individual lines at three different teller windows are listed below.

What is the GPA of a student who gets an A in a 3-credit course, a B in each of three 2-credit courses, a C in a 3-credit course, and a D in a 2-credit course? The mean grade point score is (Round to the nearest tenth as needed.)A student's course grade is based on one midterm that counts as 20% of his final grade, one class project that counts as 20% of his final grade, a set of homework assignments that counts as 50% of his final grade, and a final exam that counts as 10% of his final grade. His midterm score is 76, his project score is 96, his homework score is 78, and his final exam score is 73. What is his overall final score? What letter grade did he earn (A, B, C, D, or F)? Assume that a mean of 90 or above is an A, a mean of at least 80 but less than 90 is a B, and so on. His overall final score is (Type an integer or a decimal rounded to one decimal place as needed.)Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was 71.8 Mops. The complete list of 50 data speeds has a mean of x = 16.97 Mops and a standard deviation of s = 30.77 Mops. a. What is the difference between carrier's highest data speed and the mean of all 50 data speeds? 6. How many standard deviations is that [the difference found in part (a)]? c. Convert the carrier's highest data speed to a z score. d. If we consider data speeds that convert to z scores between - 2 and 2 to be neither significantly low nor significantly high, is the carrier's highest data speed significant? a. The difference is Mbps. (Type an integer or a decimal. Do not round.)Use z scores to compare the given values. The tallest living man at one time had a height of 237 cm. The shortest living man at that time had a height of 124.7 cm. Heights of men at that time had a mean of 170.08 cm and a standard deviation of 6.65 cm. Which of these two men had the height that was more extreme? Since the z score for the tallest man is z = and the z score for the shortest man is z = the v man had the height that was more extreme. (Round to two decimal places.)Assume that we want to construct a confidence interval. Do one of the following, as appropriate: (a) find the critical value to/2, (b) find the critical value Zo /2, or (c) state that neither the normal distribution nor the t distribution applies. Here are summary statistics for randomly selected weights of newborn girls: n = 248, x = 28.8 hg, s =7.5 hg. The confidence level is 99%. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. ta/2= (Round to two decimal places as needed.) O B. Za/2= (Round to two decimal places as needed.) O C. Neither the normal distribution nor the t distribution applies.The test statistic of z = 0.95 is obtained when testing the claim that p > 0.8. a. Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed. b. Find the P-value. c. Using a significance level of a = 0.01, should we reject Ho or should we fail to reject Ho?

P-value = (Round to three decimal places as needed.)The test statistic of z = 2.35 is obtained when testing the claim that p # 0.813. a. Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed. b. Find the P-value. c. Using a significance level of a = 0.10, should we reject Ho or should we fail to reject Ho? Click here to view page 1 of the standard normal distribution table. Click here to view page 2 of the standard normal distribution table. a. This is a two-tailed v test. b. P-value = (Round to three decimal places as needed.)Test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, and then state the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Among 2028 passenger cars in a particular region, 231 had only rear license plates. Among 380 commercial trucks, 56 had only rear license plates. A reasonable hypothesis is that commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passenger cars. Use a 0.01 significance level to test that hypothesis. a. Test the claim using a hypothesis test. b. Test the claim by constructing an appropriate confidence interval. a. Identify the null and alternative hypotheses for this test. Let population 1 correspond to the passenger cars and population 2 correspond to the commercial trucks. Let a success be a vehicle that only has a rear license plate. O A. Ho: P1 = P2 H1 : P1 # P2 B. Ho: P1 = P2 Hy: P1 P2 O D. Ho: P1 P2 Identify the test statistic. Z= (Round to two decimal places as needed.)Listed below are the numbers of words spoken in a day by each member of eight different randomly selected couples. Complete parts (a) and (b) below. Male 16, 105 26,996 1379 7518 18,969 15,228 14,105 26,518 Female 24,301 13,066 18,559 17,670 12,814 17,431 16,610 18,235 a. Use a 0.01 significance level to test the claim that among couples, males speak fewer words in a day than females. In this example, Ho is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the words spoken by the male minus words spoken by the female. What are the null and alternative hypotheses for the hypothesis test? Ho: Ha = 0 word(s) H1: Ha
