Question
One of the items on a survey instrument administered to a large statistics class at Penn State University was, "What is the maximum speed you've ever driven?". Their answers were entered into a spreadsheet under the variable name "fastest Let's assume that the survey participants (88 men and 104 women) were truthful in their responses. Use the descriptive statistics output below to answer the following questions. The fastest maximum speed driven by anyone in the class is: The slowest maximum speed driven by a female is: The speed for which 3/4 of the males had driven this fast or faster is: The number of men who had a maximum speed of 120 mph or more is: The proportion of all students in the sample who had a maximum speed of 95 mph or slower is: A student advocacy group at a large western university was interested in estimating the average rent ($) that off campus students pay per month. Five randomly selected, off-campus students were chosen and their respective monthly rent liabilities were recorded The raw data are found in Table 1. Let "x" denote the monthly rent reported Search all the thingsExplanation / Answer
1. 150
This is nothing but the maximum values among both the sample. Since maximum for female is 120 and male is 150 hence , 150 is the answer.
2. 30
Slowest maximum for a female is the minimum speed by a female driver which is 30 in this case.
3. 95
This is nothing but the Q1 of male sample. Q1 represents a values of which the rest observations lets under. So, here as the sample output for male shows that Q1 is 95.
4. 22
!20 is Q3 of male population which suggests that the 75% of the data point lies under that value. So, 1/4 lies above. So 88 x .25= 22 is the answer.
5..521
We can find it from the quantiles of male and female population.
