A researcher randomly purchases several different kits of a popular building toy. The following table shows the number of pieces in each kit in the sample. Find the median of the data. Building Toy Pieces 160 45 265 350 150 45 104 296 265 109 170 208

In this problem, we explore the effect on the mean, median, and mode of adding the same number to each data value. Consider the data set 2, 2, 3, 6, 10. (a) Compute the mode, median, and mean. (Enter your answers to one decimal place.)mode median mean (b) Add 7 to each of the data values. Compute the mode, median, and mean. (Enter your answers to one decimal place.)mode median mean (c) Compare the results of parts (a) and (b). In general, how do you think the mode, median, and mean are affected when the same constant is added to each data value in a set? -Adding the same constant c to each data value results in the mode, median, and mean decreasing by c units. -Adding the same constant c to each data value results in the mode, median, and mean remaining the same. -Adding the same constant c to each data value results in the mode, median, and mean increasing by c units. -There is no distinct pattern when the same constant is added to each data value in a set.

Determine whether the data is from a primary or secondary source. Primary       Secondary

Suppose the National Transportation Safety Board (NTSB) wants to examine the safety of compact cars, midsize cars, and full-size cars. It collects a sample of cars each of the cars types. The data below displays the frontal crash test performance percentages. Test whether there are statistical differences in the frontal crash test performance for each type of car.   Car Sizes Compact Cars Midsize Cars Full-Size Cars 95 95 93 98 98 97 87 98 92 99 89 92 99 94 84 94 88 87 99 93 88 98 99 89 What conclusions can we draw from the follow-up t-tests?   There is/are a total of  ______ statistically significant difference(s) between car type pairs out of the follow-up t-tests.  Options: a) 1 b) 2  c) 3 d) 4 e) 5 f) 6

Given the data set A = {0, 0, 12, 13, 14, 15, 16, 18, 22, 25, 30} which of the following is a true statement? O There are two modes for the data set. O The mean is greater than the median. O The mean and the median have the same value. O There is no mode for the data.

A researcher is interested in determining if there is a relationship between handedness and penmanship.  To study this question, the researcher submitted samples from 100 students to penmanship experts.  The samples were rated to be of low, medium or high penmanship quality.  The observed frequencies were totaled according to left verses right handedness.     Penmanship Handedness low medium high Left 8 29 6 right 9 37 11   Which test is appropriate for this data? Why? Calculate row, column and table totals. State the null and alternative hypothesis. What is the degree of freedom? What is the value of the test statistic? What is the p-value? Are the data statistically significant at the 5% significance level? Do you recognize any flaws in this study
