Perform the test procedure in Problem 10.99. Provide a p-value. (Assume that BMI is measured exactly with no measurement error; thus, the range 20−22.9 includes all values ≥20 and <23, etc.) 

One issue in comparing BMI between groups is the underlying distribution of BMI. The mean BMI of the 143 boys was 21.8 with sd = 3.4. The distribution of BMI was as shown in Table 10.40.

Table 10.40: Distribution of BMI among 143 high school boys

BMI ________________ Frequency

≤19.9 ……………………….. 41

20−22.9 …………………….. 65

23−25.9 ……………………. 20

26−28.9 ……………………... 9

29+ ………………………….. 8

Total ……………………... 143
