ou are applying for a job at two companies. Company A offers starting salaries with μ=$34,000 and σ=$4,000. Company B offers starting salaries with μ=$34,000 and σ=$9,000. From which company are you more likely to get an offer of ​$42,000 or​ more?

Suppose you have already calculated the mean, the average deviation, and the standard deviation of the weights in pounds of 20 third-graders.  a. if these weights were converted to kilograms and the mean and the average deviation were once again calculated, would the second average deviation be (numerically) less than, greater than, or equal to the first average deviation? Explain your answer. b. If the standard deviation of these weights were calculated in kilograms, would it be (numerically) less than, greater than, or equal to the first standard deviation? Explain your answer

We are going to calculate the mean, median, and mode for two sets of data. Please show your answer to one decimal place if necessary. Here is the first data set. 68 71 38 27 51 47 40 66 38 97 69 a. what is the mean (T) of this data set? b. What is the median of this data set? c. What is the mode of this data set? Here is the second data set. 97 71 80 29 71 55 d. What is the mean (T) of this data set? e. What is the median of this data set? f. What is the mode of this data set? 44 76 68 56

I’ve already posted this one, but I’m posting it again, because I need to be shown what to input into my TI-84 Plus calculator to solve.

6. Find the mean, median, and mode for each set of data. a. 80 90 100 110 110 140 b. 10 90 100 110 110 210 c. How do your answers for parts (a) and (b) differ (or agree)? Why?

Place the following data in a stem and leaf plot. 137 129 116 114 130 121 124 135 139 132 117 You can draw the stem and leaf plot on paper and then check your answer against the solution. You don't have to put anything in the answer box. A 13

Sam took 4 courses last semester: Spanish, Physics, Biology, and Calculus. The means and standard deviations for the final exams, and Sam's scores are given in the table below. Convert Sam's score into z scores.   Subject Mean Stand. dev. Sam's score Sam's z score Spanish 44 12 47   Physics 60 14 84.5   Biology 77 10 82   Calculus 70 12 79   On what exam did Sam have the highest relative score?(Enter the subject.) In the Biology class, there was a student with a z-score of 1.2. What score did that student earn on the exam?

For an Economics test the mean score is 100 and the standard deviation is 10, and for an Accounting test the mean score is 50 and the standard deviation is 4. You are given the test scores of a student who took both tests. Determine on which test the student had a better score. Enter E if the student did better on the Economics test Enter A if the student did better on the Accounting test Enter S if the student did relatively the same on both tests.   A student scores 125.6 on the Economics test and 60.2 on the Accounting test. The student did better/same on                test.

George has an average bowling score of 180 and bowls in a league where the average for all bowlers is 150 and the standard deviation is 20.  Bill has an average bowling score of 190 and bowls in a league where the average is 160 and the standard deviation is 15.  Who ranks higher in his own league, George or Bill? George because his standard score is higher than Bill's. Bill because his standard score is higher than George's. George because the standard deviation in his league is higher than the standard deviation in Bill's league. Bill because his 190 is higher than George's 180. Bill and George have the same rank in their leagues because both are 30 pins above the mean
