A survey asked 500 random people how often they use the bathroom on a daily basis. Nineteen percent of respondents said theyused the bathroom just once daily, 25% twice daily, 39% three times daily, 12% four times daily, 3% five times daily, and 2% sixtimes daily.Let x = the number of times a person goes to the bathroom on a daily basis. Complete the values of x from least to greatest andthe corresponding values of p(x) in the probability distribution table.Xp(x)

Carl Catcher has a batting average of .370, meaning that he makes a hit 37% of the times he is up at bat. Pete Pitcher has a batting averager of only .110. Let x be the number of times Carol comes up to bat and let y be the number of times Pete comes to bat. a. If Carl bats 7 times and Pete bats 3 times, what should ther overall batting average be? b. If a total of 50 times at bat, how many times may Pete bat in order for their combined average to be as close as possible to .300? (define 3 variables, write system and solve)
A running coach wants to know if participating in weekly running clubs significantly improves the time to run a mile. The running coach collects mean mile times for 42 runners who participate in weekly running clubs with 54 runners who do not run in clubs. The running coach measures times in January and June of the same year. All times are in seconds, and the runners all started with mile times between 8 minutes (480 seconds) and 9 minutes (540 seconds). Here are the results: (table) The running coach investigates if runners in a running club improve times more than runners not in a club. The running coach conducts a hypothesis test for the difference in sample mean change (“Running Club” minus “Not in a Club”). Here are the results: T-value = 2.7027, p-value = 0.0043, DF = 74 95% Confidence Interval (0.5254, 3.4746) Which of the following can the running coach conclude? Runners who participate in running clubs have a statistically significant change in running times when compared…
In a science fair project, Emily conducted an experiment in which she tested professional touch therapists to see if they could sense her energy field. She flipped a coin to select either her right hand or her left hand, and then she asked the therapists to identify the selected hand by placing their hand just under Emily's hand without seeing it and without touching it. Among 350 trials, the touch therapists were correct 165 times. Complete parts (a) through (d).
A physician wants to see if there was a difference in the average smokers' daily cigarette consumption after wearing a nicotine patch. The physician set up a study to track daily smoking consumption. In the study, the patients were given a placebo patch that did not contain nicotine for 4 weeks, then a nicotine patch for the following 4 weeks. Test to see if there was a difference in the average smoker's daily cigarette consumption using α = 0.01.

In a study on the ecological impact of malarial infection in the lizard Scelopons occidentalis, researchers caught 15 lizards with the malarial parasite Plasmodium and 15 without. Researchers measured the distance (meters) each lizard could run in two minutes (as a measure of stamina). The following is the code and R output from the "t.test" function. t.test (x=infected, y=uninfected) Welch Two Sample t-test data: infected and uninfected t = -1.9658, df = 27.239, p-value = 0.05959 alternative hypothesis: true difference in means is not equal to 0 95 percent confidence interval: -10.9523489 0.2323489 sample estimates: mean of x mean of y 26.87333 32.23333 What is the upper bound of the confidence interval?

The histogram displays the number of 2008 births among U.S. women ages 10 to 50 . Each bin represents an interval of two years, and the height of each bin represents the frequency with which the data fall within that interval. A histogram for the number of births by mother’s age for 2008. Height of 62 for ages 14 to 16, height of 202 for ages 16 to 18, height of 369 for ages 18 to 20, height of 415 for ages 20 to 22, height of 441 for ages 22 to 24, height of 470 for ages 24 to 26, height of 487 for ages 26 to 28, height of 460 for ages 28 to 30, height of 403 for ages 30 to 32, height of 326 for ages 32 to 34, height of 252 for ages 34 to 36, height of 177 for ages 36 to 38, height of 99 for ages 38 to 40, height of 46 for ages 40 to 42, height of 17 for ages 42 to 44, and height of 4 for ages 44 to 46. Use the provided histogram to answer questions about the number of births for each age group. How many births occurred among women over the age of 38 ? number of births:What percentage…
