3. In 2010, the United Nations claimed that there was a higher rate of illiteracy in men thanin women from the country of Qatar. A humanitarian organization tested reading abilityin a random sample of Qataris. The results revealed that 45 out of 234 men and 42 out of251 women were illiterate. Do these results indicate that the United Nations findingswere correct?a. State your null and altenative hypotheses.b. If you pool the men and women together, what percent of the overall sample is illiterate?c. Calculate the standard error and draw and label the sampling distribution.d. Calculate a test statistic and P-value.e. Explain what your P-value means in this context.f. If a (alpha) = .1, what do you conclude?

Let's examine the mean of the numbers 1, 2, 3, 4, 5, 6, 7, and 8 by drawing samples from these values, calculating the mean of each sample, and then considering the sampling distribution of the mean. To do this, suppose you perform an experiment in which you roll an eight-sided die two times (or equivalently, roll two eight-sided dice one time) and calculate the mean of your sample. Remember that your population is the numbers 1, 2, 3, 4, 5, 6, 7, and 8. The true mean (µ) of the numbers 1, 2, 3, 4, 5, 6, 7, and 8 is , and the true standard deviation (o) is The number of possible different samples (each of size n = 2) is the number of possibilities on the first roll (8) times the number of possibilities on the second roll (also 8), or 8(8) = 64. If you collected all of these possible samples, the mean of your sampling distribution of means (µM) would equal and the standard deviation of your sampling distribution of means (that is, the standard error or ɑm) would be The following chart…
Consider a population proportion p = 0.27. Calculate the standard error for the sampling distribution of the sample proportion when n = 17 and n = 65?
You are the operations manager for an airline and you are considering a higher fare level for passengers in aisle seats. How many randomly selected air passengers must you survey? Assume that you want to be 95% confident that the sample percentage is within 5.5 percentage points of the true population percentage. Complete parts (a) and (b) below. a. Assume that nothing is known about the percentage of passengers who prefer aisle seats. n = (Round up to the nearest integer.) b. Assume that a prior survey suggests that about 34% of air passengers prefer an aisle seat. n = IDound un to the nearest integer)
In a random sample of 68 people,17 are classified as "successful." a. Determine the sample proportion, p, of "successful" people. b. If the population proportion is 0.70,determine the standard error of the proportion.
4. Suppose that 15% of all students at your school ride a bicycle to class each day. Suppose further that you take a random sample of 80 students at your school. a. Is 15% number a parameter or a statistic? Explain briefly. b. Are you guaranteed that 15% of your sample ride a bicycle to class each day? Explain briefly. c. Describe the sampling distribution of the sample proportion of these 80 students who ride a bicycle to class each day. (Hint: Be sure to refer to the shape, center, and spread of this sampling distribution.) Also include a well- labeled sketch of this distribution. HCL SYstem
You are the operations manager for an airline and you are considering a higher fare level for passengers in aisle seats. How many randomly selected air passengers must you survey? Assume that you want to be 99% confident that the sample percentage is within 4.5 percentage points of the true population percentage. Complete parts (a) and (b) below. a. Assume that nothing is known about the percentage of passengers who prefer aisle seats. n = 820 (Round up to the nearest integer.) b. Assume that a prior survey suggests that about 39% of air passengers prefer an aisle seat. n=0 (Round up to the nearest integer.) C
