Answer:
Option B
<em>The best point estimate of the proportion of people attending the game who believe that the concession stand should be closer to the stands is:</em>
<em>p = 0.72.</em>
Step-by-step explanation:
We want to estimate the proportion of people who feel that the stand should be closer to the stands.
We have a sample of 150 people, of which 108 think that the stand should be closer to the stands.
A point estimator for the proportion p is 
.
Where
Where n represents the size of the sample and represents the number of favorable cases.
We know that 
and 
.
Then we can estimate p by the estimator
I would try b the rise\run is 2\2 so give it a go
Here’s the answer and each step I took to solve it. With the example I made on the side just continue to repeat that for each one to get the answers. You just replace that one number for the X to take the place for the next X value as you go down the table solving them.
Answer:
To give more clarity to the question, lets examine the attached back-to-back stem plot.
A)
Having examined the stem plot, we can using quick calculations, summarize that:
The mean (40.45 cal/kg) and median (41 cal/kg) daily caloric intake of ninth-grade students in the rural school is higher than the corresponding measures of center, mean (32.6 cal/kg) and median (32 cal/kg), for ninth-graders in the urban school.
The median and the mean for the students in the 9th grade in the urban school is lower than that of those of their contemporaries in the rural school. The respective medians and means are stated below:
Urban 9th Grade Students
Median = 32 cal/kg
Mean = 36 cal/kg
Rural 9th Grade Students
Median = 41 cal/kg
Mean = 41 cal/kg
Please note that all figures above have been approximated to the nearest whole number.
B)
It is unreasonable to generalize the findings of this study to all rural and urban 9th-grade students in the United States because the sample is too small compared to the target population size.
To allow for generalization, they would have to collect and analyze more samples say from every state within America.
Cheers!
