In each of Exercises, we have given the number of successes and the sample size for a simple random sample from a population. In each case, a. use the one-proportion plus-four z-interval procedure to find the required confidence interval.b. compare your result with the corresponding confidence interval found in Exercises, if finding such a confidence interval was appropriate. In each of Exercises, we have given the number of successes and the sample size for a simple random sample from a population. In each case, do the following tasks. a.Determine the sample proportion.b.Decide whether using the one-proportion z-interval procedure is appropriate.c.If appropriate, use the one-proportion z-interval procedure to find the confidence interval at the specified confidence level.d.If appropriate, find the margin of error for the estimate of p and express the confidence interval in terms of the sample proportion and the margin of error. x = 8, n = 40, 95% levelx = 10, n = 40, 90% levelx = 35, n = 50, 99% levelx = 16, n = 20, 90% levelx = 3, n = 100, 99% levelx = 40, n = 50, 95% level

In each of Exercises, we have given the number of successes and the sample size for a simple random sample from a population.
In each case, do the following tasks.
a.Determine the sample proportion.
b.Decide whether using the one-proportion z-interval procedure is appropriate.
c.If appropriate, use the one-proportion z-interval procedure to find the confidence interval at the specified confidence level.
d.If appropriate, find the margin of error for the estimate of p and express the confidence interval in terms of the sample proportion and the margin of error.
x = 8, n = 40, 95% level
x = 10, n = 40, 90% level
x = 35, n = 50, 99% level
x = 16, n = 20, 90% level
x = 3, n = 100, 99% level
x = 40, n = 50, 95% level
