- Scores on a test have a mean of 66 and a standard diviation of 9. Michelle has a score of 57. Convert Michelles score to z-score.Given X ~ N(300, 15). What can be said of the median? Group of answer choices The median is the same as the mode and the average. It is less than the average. It is the same as the mode. It is the same as the average.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
- General Social Survey (GSS) 2006 collected the data of the number of people in each household in the U.S. The variable name is "hompop."ences in your response. Investigation 2: Songs from Spotify - Mode and Popularity A random sample of 3439 songs was selected from the Spotify database and twelve variables were measured for each song. Remember, the Mode variable indicates the type of scale the song's melodic content is derived from (Major or Minor). Popularity is on a scale of 0 to 100 and songs with higher numbers are more popular. Let us now investigate whether Major songs are significantly more "Popular" than Minor songs. Let us define "Popular" as songs that earned a popularity rating of 50 or higher. From the random sample of songs, there were 1964 Major songs and of those 853 were rated "Popular." In addition, there were 1475 Minor songs and of those 587 were rated "Popular." In this invesligation we will subtract (Major - Minor). a) Define the population parameter using context and symbols in one complete sentence. b) State the hypotheses using the claim. c) Check the specific conditions necessary to consider…☐True ☐FalseCorrelation coefficient and coefficient of determination are two ways of saying the same thing.
