Question 15 In general, if a decision was made to reject the null hypothesis, one can conclude that: a. There is significant evidence that the alternative hypothesis is true. b. There is not significant evidence that the alternative hypothesis is true. c. There is significant evidence that the null hypothesis is true. O d. None of the above choices are true.

If a researcher fails to reject the null hypothesis, he or she can conclude that:   Question 35 options:   the null hypothesis is true.   the alternative hypothesis is true.   there is adequate evidence to reject the null.   there is no adequate evidence to reject the null.

House values in Martin, TN are known to have a distribution that is skewed to the right instead of being normally distributed.  Assume that house values in Martin, TN have a mean of $64,500 with a standard deviation of $21,350.  Answer the following probability questions concerning house values in Martin, TN. Part 1:   If 1 randomly selected house in Martin, TN is selected, what is the probability that this house has a value under $60,000?     Part 2:  If 30 randomly selected houses in Martin, TN are selected, use the Central Limit Theorem to determine the probability that their average value is under $60,000?

Questions 1 and 2: Set up the Null and Alternative hypotheses to test the following claims: 1.

Thus, Jack accuses Fred of having an unfair diethat doesn’t land on Box Cars (six’s) as often as it should. To decide, Jack rolls the die 30 times and it lands on Box Cars only 12% of the time.
