(a)
To explain the 87th percentile for weight and 67th percentile for height.
(a)

Explanation of Solution
A percentile defines that a certain percent of data falls less than that now the 87th percentile of weight means the girl’s weight is more than 87% of the other girls of her age or it can be said that 87% girl’s weight is less than her weight.
Similarly, 67th percentile in height means that 67% of the other girls height is less than the her height or it can be said that her height is more that 67% of the girls of her age.
(b)
To explain the 85th percentile of vehicle speed.
(b)

Explanation of Solution
Here, the speed limit is 85th percentile, which means that the vehicles speed should be less that 85% of all the vehicles speed, for e.g., if 100 vehicles are going through the road then the vehicles speed should be out of the 85% of the lower speed.

For this group, their average serum cholesterol is 188.4 (measured in mg/100mL). Suppose that the total serum cholesterol measurements are normally distributed with standard deviation of 40.7. (a) Find a 95% confidence interval of the mean serum cholesterol of patients on the special diet.arrow_forwardThe accompanying data represent the weights (in grams) of a simple random sample of 10 M&M plain candies.

Students in an online course are each randomly assigned to receive either standard practice exercises or adaptivepractice exercises. For the adaptive practice exercises, the next question asked is determined by whether the studentgot the previous question correct. The teacher of the course wants to determine whether there is a differencebetween the two practice exercise types by comparing the proportion of students who pass the course from eachgroup. The teacher plans to test the null hypothesis that versus the alternative hypothesis , whererepresents the proportion of students who would pass the course using standard practice exercises andrepresents the proportion of students who would pass the course using adaptive practice exercises.The teacher knows that the percent confidence interval for the difference in proportion of students passing thecourse for the two practice exercise types (standard minus adaptive) is and the percent…arrow_forward
