Answer:
it would be 1
Step-by-step explanation:
Using the normal distribution, there is a 0.4826 = 48.26% probability that the sample mean is between 15 and 16 grams per day.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean
and standard deviation
is given by:

- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
- By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation
.
For this problem, the parameters are given as follows:

The probability is the <u>p-value of Z when X = 16 subtracted by the p-value of Z when X = 15</u>, hence:
X = 16:

By the Central Limit Theorem


Z = 2.11
Z = 2.11 has a p-value of 0.9826.
X = 15:


Z = 0
Z = 0 has a p-value of 0.5.
0.9826 - 0.5 = 0.4826 = 48.26% probability that the sample mean is between 15 and 16 grams per day.

Answer:

Step-by-step explanation:
Given that,
The perimeter of the base of pyramid, P = 10.7 ft
The height of the pyramid, h = 9.8 ft
We need to find the volume of the pyramid.
The perimeter of square is given by :
4s = 10.7, s is side
s = 2.675 ft
Now the volume of pyramid is given by :

So, the volume of the pyramid is equal to
.
