An athletic trainer wants to see if a new treatment procedure for ankle sprains results in less ankle swelling than standard treatment 24 hours following the injury. Over several months, 30 athletes with ankle sprains are randomly assigned to receive either the standard care or new treatment procedure. Ankle swelling is measured using water displacement in both groups. Which t-test should be used to determine if one procedure resulted in more or less swelling than the other

Please see below. I am only given one attempt at this problem; please help.  Marc takes a random sample of 14 dogs from the local animal shelter and weighs them. He obtains the following data: 9 25 32 40 41 45 47 50 53 53 62 79 94 106 What is the third quartile (Q3) for this data? Use the method from the book and videos, not Minitab.

A statistical program is recommended. The National Football League (NFL) records a variety of performance data for individuals and teams. To investigate the importance of passing on the percentage of games won by a team, the following data show the conference (Conf), average number of passing yards per attempt (Yds/Att), the number of interceptions thrown per attempt (Int/Att), and the percentage of games won (Win%) for a random sample of 16 NFL teams for one full season. Team Conf Yds/Att Int/Att Win% Arizona Cardinals NFC 6.5 0.042 50.0 Atlanta Falcons NFC 7.1 0.022 62.5 Carolina Panthers NFC 7.4 0.033 37.5 Cincinnati Bengals AFC 6.2 0.026 56.3 Detroit Lions NFC 7.2 0.024 62.5 Green Bay Packers NFC 8.9 0.014 93.8 Houstan Texans AFC 7.5 0.019 62.5 Indianapolis Colts AFC 5.6 0.026 12.5 Jacksonville Jaguars AFC 4.6 0.032 31.3 Minnesota Vikings NFC 5.8 0.033 18.8 New England Patriots AFC 8.3 0.020 81.3 New Orleans Saints NFC 8.1 0.021 81.3 Oakland Raiders AFC…

While the mail-order DVD rental market has slowed with the advent of streaming, mail-order is still the only way to find rare movies. Raredvds.biz is considering moving into the rental business after considerable success selling DVDs. To gauge their customer service, they are considering the case of the 1980 film The Monster Club featuring Vincent Price. Raredvds.biz expects to have one copy of the DVD. Based on data collected from customers, Raredvds.biz believes that the average time between orders for the film will be about 10 days with a coefficient of variation of one. Using customer data, the company also believes that including shipping time, both ways, the DVD will on average spend seven days in service, with a coefficient of variation of one. How long does a customer wait on average before being shipped the DVD?

A researcher hypothesized that cytokinins and auxins supplied by tumor-inducing insects lead to the production of tumors in plants. She performed experiments in which she hypodermically injected green pepper plants to determine if she could induce tumors. In one experiment she varied the concentration of cytokinin and the ratio of auxin concentration to cytokinin concentration. She used 3 concentrations of cytokinin and 6 ratios of auxin/cytokinin. The concentrations are indexed (1-3) with 3 indicating the highest concentration of cytokinin. The 6 ratios of auxin/cytokinin varied from 0.125 to 5.0 with values greater than 1 indicating that auxin was in greater concentration than cytokinin. The resulting data are in the date file "auxcyt.csv". The measured sizes of the tumors induced (relative to controls) are given in the 3rd column ('sumdiffd'). Analyze these data testing the appropriate hypotheses and interpret the results. (Note the unequal sample sizes.) auxcyt data…

Student Activity: Using MS Excel Directions: Study the following situation and do the task. Then answer the following questions or supply the missing information. Submission: Upload the MS EXCEL sheet with the completed interpretation of results. Mr. Santiago's company sells bottled coconut juice. He claims that a bottle contains 500 ml of such juice. A consumer group wanted to know if his claim is true. They took six random samples of 10 such bottles and obtained the capacity, in ml, of each bottle. The result is shown as follows: Sample 1 Sample 2 Sample 3 Sample 4 Sample 5 Sample 6 500 500 497 501 502 496 498 500 497 495 497 497 497 495 502 500 497 496 503 494 496 497 499 495 499 498 497 497 496 497 497 500 497 500 497 497 497 500 497 500 497 500 497 500 497 495 499 500 497 500 497 497 500 496 495 497 495 497 500 497 Assuming that the measurements were carefully obtained and that the only kind of error present is the sampling error, what is the point…

Construct a stem-and-leaf display of the data.  What appears to be a representative strength  value? Do the observations appear to be highly  concentrated about the representative value or  rather spread out?  b. Does the display appear to be reasonably symmetric about a representative value, or would you describe its shape in some other way?  c. Do there appear to be any outlying strength  values?  d. What proportion of strength observations in this  sample exceed 10 MPa?  The strength data for beams is attached

A researcher wanted to determine if carpeted rooms contain more bacteria than uncarpeted rooms. The table shows the results for the number of bacteria per cubic foot for both types of rooms.   Full data set      Carpeted   Uncarpeted 14.214.2 15.415.4 1616 6.46.4 6.76.7 7.97.9 9.79.7 8.38.3 7.57.5 8.38.3 12.412.4 11.911.9 9.99.9 13.613.6   9.59.5 7.67.6   Determine whether carpeted rooms have more bacteria than uncarpeted rooms at the alpha equals 0.05α=0.05 level of significance. Normal probability plots indicate that the data are approximately normal and boxplots indicate that there are no outliers. State the null and alternative hypotheses. Let population 1 be carpeted rooms and population 2 be uncarpeted rooms.     A. Upper H 0H0​: mu 1 less than mu 2μ1<μ2 Upper H 1H1​: mu 1 greater than mu 2μ1>μ2   B.

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).
