# Question: In a population 100 and x 25

In a population, µ = 100 and σx = 25. A sample (N = 150) has X = 102. Using two tails of the sampling distribution and the .05 criterion:

(a) What is the critical value?

(b) Is this sample in the region of rejection? How do you know?

(c) What does this indicate about the likelihood of this sample occurring in this population?

(d) What should we conclude about the sample?

The mean of a population of raw scores is 33 (σx = 12). Use the criterion of .05 and the upper tail of the sampling distribution to test whether a sample with X = 36.8 (N = 30) represents this population. (a) What is the ...(a) In question 20, if a particular sample does not represent the population of average bowlers, what is your best estimate of the µ of the population it does represent? (b) Explain the logic behind this conclusion. (a) What is sampling with replacement? (b) What is sampling without replacement? (c) How does sampling without replacement affect the probability of events, compared to sampling with replacement? Listening to music while taking a test may be relaxing or distracting. We test 49 participants while listening to music, and they produce an X = 54.36. The mean of the population taking this test without music is 50 (aX = ...We ask if visual memory ability for a sample of 25 art majors (X = 49) is better than that of engineers who, on a nationwide test, scored p = 45 and σX = 14. Higher scores indicate a better memory. (a) Is this a one- or ...Post your question
