Considering the given data-set, we have that:
- The lowest batting average is of 0.254.
- On the histogram, 5 values would fall into the class 0.251 - 0.280.
<h3>What is an histogram?</h3>
An histogram is a graph that shows the number of times each element of x was observed, or the number of elements x in a range of values, as is used for this problem.
For the given 20 batting averages given in the table, we have that:
- Looking at all of them, the lowest value of the table is of 0.254, hence the lowest batting average is of 0.254.
- The measures in the table between 0.251 and 0.28 are: 0.277, 0.265, 0.267, 0.259, 0.254. Hence, this means that on the histogram, 5 values would fall into the class 0.251 - 0.280.

I think a is the corrcet answer???
Answer:
Yes
Step-by-step explanation:
A whole number means that there is no decimal place inside the number. Even if the number is negative, if the number doesn't have a deciaml place, it means that it is a whole number.
Answer:
90% confidence interval for the mean weight loss for the population represented by this sample assuming that the differences are coming from a normally distributed population is [1.989 ,13.5105]
Step-by-step explanation:
The data given is
Mean Std Dev
Before 177.25 29.325
After 169.50 22.431
Difference 7.75 8.598
Hence d`= 7.75 and sd= 8.598
The 90% confidence interval for the difference in means for the paired observation is given by
d` ± t∝/2(n-1) *sd/√n
Here t∝/2(n-1)=1.895 where n-1= 8-1= 7 d.f
and ∝/2= 0.1/2=0.05
Putting the values
d` ± t∝/2(n-1) *sd/√n
7.75 ±1.895 * 8.598 /√8
7.75 ± 5.7605
1.989 ,13.5105
90% confidence interval for the mean weight loss for the population represented by this sample assuming that the differences are coming from a normally distributed population is [1.989 ,13.5105]
185 since it is going by ones, Hope that helped. :)
