## A random sample of 25 statistics examinations was taken. the average score in the sample was 76 with a standard deviation of 12. assuming the scores are normally distributed, the 99% confidence interval for the population average examination score is:

Since the sample size is less than 30, therefore we use the t statistic. Let us define the given variables: N = sample size = 25 X = average score = 76 s = standard deviation = 12 99% Confidence interval Degrees of freedom = n – 1 = 24 …

## What price do farmers get for the peach crops? in the third week of June, a random sample of 40 farming regions gave a sample mean of \$6.88 per basket. assume that the standard deviation is known to be \$1.92 per basket. find a 90% confidence interval for the population mean price per basket that farmers in this region get for their peach crop

Given:Sample size, n = 40Sample mean, xb = \$6.88Population std. deviation, σ = \$1.92 (known)Confidence interval = 90% Assume normal distribution for the population.The confidence interval is(xb + 1.645*(σ/√n), xb – 1.645*(σ/√n)= (6.88 + (1.645*1.92)/√40, 6.88 – (1.645*1.92)/√40)= (7.38, 6.38) Answer: The 90% confidence interval is (7.38, 6.38)

## Consider college officials in admissions registration, counseling, financial aid campus ministry, food services, and so on. How much money do these people make each year? Suppose you read in your local newspaper that 45 officials in student services earn an average of \$50,340 each year. Assume that the standard deviation is \$10,780 for salaries of college officials and student services. Find a 90% confidence interval for the population mean salaries of such personnel. Round your answer to the nearest dollar and don;t forget to use the \$ sign.

Since sample size is > 40, we use the z-score in calculating for the confidence interval. The formula is given as: Confidence Interval = X ± z * σ / sqrt (n) Where, X = mean = \$50,340 z = z-score which is taken from standard distribution tables at 90% …

## Studies continue to prove that if a girl stays in school she will strengthen her family, community, and nation. A long list of benefits of educating a girl in a developing country compiled by the World Health Organization includes later marriages, smaller families, better hygiene, greatly increased likelihood that further children will receive education, and my favorite – greater confidence. A bicycle is a simple, sustainable tool that eases long travel distances and encourages girls to stay in school. —Foreword to Wheels of Change, Leah Missbach Day What is the central idea of this passage from the foreword?

Mahtematical and statistical reasoning makes it evident that there is a mistake in the writing of the question and the digits were duplicated. So the right question is: “You need to have a password with 5 letters followed by 3 odd digits between 0 and 9, inclusive. If the characters …

## Find the critical value zα/2 that corresponds to a 98% confidence level.

So hmm check the picture below, that’s about the circle and the endpoints, but notice, the endpoints make up a segment, namely the diameter of the circle, well…. let’s see how long that is, because, the radius is half the diameter now.. hmmm notice, the midpoint of the diameter, is …

## The director of a customer service center wants to estimate the mean number of customer calls the center handles each day, so he randomly samples 26 different days and records the number of calls. the sample yields a mean of 258.4 calls with a standard deviation of 32.7 calls per day. the 95% confidence interval for the mean number of calls per day has an upper bound of ________. (round your answer to 1 decimal place.)

First we calculate for the total number of possibilities (permutation) to select 4 disks from the container: Total number of possibilities = 10 * 9 * 8 * 7 Total number of possibilities = 5040 Now let us find the 4 disks that will result in a range of 7. …
