a) 0.16
b) 0.0518
c)
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
For a proportion p in a sample of size n, we have that the mean is and the standard deviation is
In this problem, we have that:
a. Find the mean of p, where p is the proportion of minority member applications in a random sample of 2100 that is drawn from all applications.
The mean of p is 0.16.
b. Find the standard deviation of p.
c. Compute an approximation for P ( p leq 0.15), which is the probability that there will be 15% or fewer minority member applications in a random sample of 2100 drawn from all applications. Round your answer to four decimal places.
This is the pvalue of Z when X = 0.15. So
has a pvalue of 0.4247
Answer:
448
Step-by-step explanation:
Assuming that each notebook contains the same amount of pages, you must first divide 512 by 8. You will find that each notebook contains 64 pages. Then, to find how many pages he filled with notes after completing 7 notebooks, multiply 64 by 7. You should get the answer, 448.
