A population proportion is 0.59. Suppose a random sample of 661 items is sampled randomly from this population. Appendix A Statistical Tables a. What is the probability that the sample proportion is greater than 0.60? b. What is the probability that the sample proportion is between 0.57 and O.63? c. What is the probability that the sample proportion is greater than 0.57?

You are given the following set of observations:  98, 77, 26, 33, 88, 90, 79, 81.  What would be the mean for this distribution?

Suppose a random sample of 880 athletes from the college are asked what their major is. The table below shows the results of the survey. Observed Frequencies of Majors from the Sample Outcome Observed Frequency Math/Science 234 Arts & Humanities 240 Business & Economics 132 Other 274 The distribution of majors at the college is shown in the second column of the table below.   Fill in the expected frequencies.  (Round to the nearest whole number). Frequencies of Majors at the College Outcome Expected Percent Expected Frequency Math/Science 31   Arts & Humanities 19   Business & Economics 30   Other 20

Review the data that appears: A population is made up of N= 5, these being 1, 3, 5, 6 and 7. • If a sample of size n= 3 is selected without replacement, construct the sampling distribution for the sample median. Help yourself in this step with the following table and in the anthology. • Prepare the probability histogram of the sample median.
