Compare and contrast the benefits and drawbacks of employing sampling to limit the amount of data items that must be shown. Is simple random sampling (without replacement) a viable sampling strategy? Why do you think that is?

Below n is the sample size, p is the population and p is the sample proportion.use the central limit theorem and th to-84 probability n=148 P=0.14

Your firm is conducting a study among employees about their attitudes toward union membership. Management needs a sampling design that is likely to reflect the true feelings of all employees but is efficient to draw. You must design a ____.   Multiple Choice   probability simple random sample   nonprobability convenience sample   nonprobability judgement sample   probability cluster sample   probability systematic sample

the difference between the sample result and the result of an accurate census is called......   options are  random sampling error systematic sampling error primary sampling error secondary sampling error

A publisher reports that 67% of their readers own a personal computer. A marketing executive wants to test the claim that the percentage is actually over the reported percentage. A random sample of 160 found that 71% of the readers owned a personal computer. Is there sufficient evidence at the 0.01 level to support the executive's claim? Step 1 of 6: State the null and alternative hypotheses. Step 2 of 6: Find the value of the test statistic. Round your answer to two decimal places. Step 3 of 6: Specify if the test is one-tailed or two-tailed. Step 4 of 6: Determine the decision rule for rejecting the null hypothesis, H0H0. Step 5 of 6: Make the decision to reject or fail to reject the null hypothesis. Step 6 of 6: State the conclusion of the hypothesis test.

What is the meaning of x ~ N (50, 20)?   1. Sampling distribution of x is distributed with a mean of 20 and a standard deviation of 50   2. x-bar is normally distributed with a mean of 20 and a standard deviation of 50   3. x is normally distributed with a mean of 50 and a standard deviation of 20   4. Sampling distribution of x is distributed with a mean of  50 and a standard deviation of 20

I used excel and got a 1.31 on this question, but my friend got another answer.

elect the scenario below that demonstrates sampling bias. Select the correct answer below: A study is conducted about which type of a credit card customers prefer. The employees of American Express Co. were used as the sample. A hospital conducts a study about the quality of a new MRI machine. All patients who use the machine were used as the sample.
