Answer:
And we can find the probability using the complement rule and with the normal standard table like this:
The probability that the mean height for the sample is greater than 65 inches is 0.007
Step-by-step explanation:
Let X the random variable that represent the women heights of a population, and we know the following parameters
and
We are interested on this probability
Since the sample size selected is 75>30 we can use the centrel limit theorem and the appropiate formula to use would be the z score given by:
If we find the z score for 65 inches we got:
And we can find the probability using the complement rule and with the normal standard table like this:
The probability that the mean height for the sample is greater than 65 inches is 0.007
114
1) Gathering the data
The mean is calculated by adding all the numbers and divided by the number of observations in this case 5.
So, Laura needs to score 114 to get at least 94 as an average.
