Answer:
i think e because we do not know the y or z values
Step-by-step explanation:
Answer:
Explained below.
Step-by-step explanation:
According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
The mean of this sampling distribution of sample proportion is:
The standard deviation of this sampling distribution of sample proportion is:
A random sample of <em>n</em> = 658 items is sampled randomly from this population.
As the sample size is large, i.e. <em>n</em> = 658 > 30, the Central limit theorem can be applied to approximate the sampling distribution of sample proportion by a Normal distribution.
Compute the mean and standard deviation as follows:
(a)
Compute the probability that the sample proportion is greater than 0.63 as follows:
(b)
Compute the probability that the sample proportion is between 0.60 and 0.66 as follows:
(c)
Compute the probability that the sample proportion is greater than 0.592 as follows:
(d)
Compute the probability that the sample proportion is between 0.57 and 0.60 as follows:
(e)
Compute the probability that the sample proportion is less than 0.51 as follows:
Answer:
you can type it into a calculator you know. it gives the right answer

It seems that you have missed the necessary options for us to answer this question so I had to look for it. So here is the answer. <span>Sarabeth used a box-and-whisker plot to summarize her race times in minutes. She didn't include her latest race time of 28 minutes so the inclusion of this new time would affect the box-and-whisker plot is that, the median will increase. Hope this helps.</span>
