Problem 8

In Problems 5–8, determine whether the random variable is discrete or continuous. In each case, state the possible values of the random variable.

(a) The number of defects in a roll of carpet.

(b) The distance a baseball travels in the air after being hit.

(c) The number of points scored during a basketball game.

(d) The square footage of a house.

Step-by-Step Solution:

Step 1 of 5) Whether the random variable is discrete or continuous. In each case, state the possible values of the random variable. (a) The number of defects in a roll of carpet. (b) The distance a baseball travels in the air after being hit. (c) The number of points scored during a basketball game. (d) The square footage of a house. Expected Frequencies in a Chi-Square Test for Independence To fnd the expected frequency in a cell when performing a chi-square independence test, multiply the cell’s row total by its column total and divide this result by the table total. That is, Expected frequency = 1row total21column total2 table total. This result is close to that obtained in Table 8 (the difference exists because of rounding error; in fact, 435.024 is more accurate). We need a test statistic and sampling distribution to see whether the expected and observed counts are significantly different. Test Statistic for the Test of Independence Let Oi represent the observed number of counts in the ith cell and Ei represent the expected number of counts in the ith cell.
