Another measure of central tendency that is rarely used but iseasy to calculate is the midrange. It can be found using theformula below. A consumer testing service obtained themileages (in miles per gallon) shown in the table to the right infive test runs performed with three types of compact cars. Eachcar manufacturer wants to advertize that its car performed thebest in this test. Which of the car manufacturers of cars A, B, andC would prefer to use the midrange statistic in their ads? Explainyour reasoning.Midrange=(Maximum data entry) + (Minimum data entry)2A2833The manufacturer of(Type an integer or a decimal.)282935Car MPGB3230322532...C3033243331would prefer to use the midrange, since their car's midrange of mpg is theof the three models.

During one shift, the express lane clerk recorded how many times customers violated the "10 items or less" rule for his lane. In particular, he recorded how many items over the limit each violator placed on the conveyor belt. This data is summarized in the histogram below. NOTE: The last class actually represents "7 or more items," not just 7 items. Frequency 12+ 298 ans = 10- a 2 0.5 1.5 2.5 3.5 4.5 5.5 6.5 7.5 # items over 10 What is the frequency of times the limit was exceeded by at least 3 items?

One study investigated whether the thickness of the banana peel is related to the banana variety and the fertilizer used. The research examined 4 different banana varieties and 3 different fertilizers.The following values were calculated from the data:SSr = 3.4 SSc =1.3 SSe =1.2The research first set out to find out if there is a difference in the average thickness of the banana peel between the fertilizers used. The used fertilizers are presented in the material with columns.Calculate the p-value of the test. Give the answer to two decimal places. Remember the correct decimal separator.

A poll was conducted on a representative sample of 600 adults living in the United States in order to investigate the decline in cable and satellite TV subscriptions. For this sample, 150 adults revealed that they are "cord cutters," (that is, they canceled their cable/satellite TV service and now only use a video streaming service). You want to estimate p, the true proportion of all US adults who are "cord cutters." Complete parts a through e. d. Give a practical interpretation of the confidence interval from part c.

In Major League baseball, the speed of a pitch is very important. How fast is the speed of a major league pitchers average pitch? A researcher took a random sample of the speed of 16 pitches from the 2019 Major League baseball season. The following are the speeds of these pitches in miles per hour: 92.8, 87.0, 89.1, 96.2, 75.6, 89.6, 92.5, 83.3, 86.5, 95.6, 94.1, 91.6, 94.2, 93.4, 90.0 It is reasonable to treat these measurements as coming from a normal distribution with unknown mean μ and unknown standard deviation σ d) Find the sample standard deviation of the above data e) Find the sample median of the above data. f)Create a 90% confidence interval for μ.

The accompanying table shows the height and weight of five football players in training camp. The body mass index (BMI) is used to assess the relative amount of fat in a person's body. If w is weight in pounds and h is height in inches, then BMI = 703wh. Some physicians consider your body fat abnormal if your BMI satisfies BMI-23>3. Which of the five players does not have abnormal body fat? does not have abnormal body fat. Player D Player B Player C Player E Player A .. Player A B C E Ht. 6-8 5-8 5-10 5-9 6-6 Wt. 359 240 227 164 342
