Answer #1

above stated hypothesis is true for comparing length of sentence written by men and women judge for same crime

we will rewrite it

H0 : Average length of sentence written by men judge is longer than women judge

against

H1: Average length of sentence written by men judge is not longer than women judge for same crime

H0 : mu1> mu2 against. H1 : mu1< mu2

mu1 : Average length of sentence written by men judge

mu2 : Average length of sentence written by women judge

8. In the population, there is no difference between men and women on a certain test. However, the mean for men was higher than the mean for women in your sample, and with a t of 4.532 and a p-value of .004, you have determined it is appropriate to reject the null hypothesis and conclude a difference does exist.

Please answer True or False for the following statements: 1.) In hypothesis testing, if the null hypothesis is rejected, then the alternative or motivated hypothesis must also be rejected. 2.) Under certain conditions, binomial distributions can be approximated by normal distributions. 3.) Using a normal distribution to approximate binomial probabilities is extremely accurate, but takes an excessive amount of time and should be avoided. 4.) A bell-shaped curve is still normal, even if the mean, median, and mode are not...

Suppose that 70% of men and 30% of women in a state support the incumbent candidate for the governor. Assume that the numbers of men and women in the state are equal. (a) Suppose 500 people are surveyed at random, and ^p1 is the proportion of people surveyed who say they support the incumbent. What is the variance of ^p1? (b) Suppose that 250 men and 250 women are surveyed at random, and ^p2 is the proportion of people surveyed...

True or False 1. Hypothesis tests are robust to the significance level you choose, meaning regardless of the alpha level: .10, .05, or .01, our test will have the same conclusion or result. 2. If alpha is greater than the p-value, then we reject the null hypothesis. 3. The p-value is strictly the probability the null hypothesis being true. 4. Hypothesis tests are accessing the evidence provided by the data and deciding between two competing hypotheses about the population parameter....

Men tend to have longer feet than women. So, if you find a really long footprint at the scene of a crime, then in the absence of any other evidence, you would probably conclude that the criminal was a man. And conversely, if you find a really short footprint at the scene of a crime, then (again in the absence of any other information) you would probably conclude that the criminal was a woman. Where should the cut-offvalue be for...

Please limit each response to no more than 3 sentences. i) A p-value is the probability that the null hypothesis is false. ii) A chi-square test statistic can never be negative. iii) If we reject the null hypothesis that a population proportion is equal to a specific value, then that specific value will not be contained in the associated confidence interval. iv) If...

True/False 1. Suppose we know for a fact that on a certain memory test, recognition is not any better than recall. However, the P-value for the data from your sample is 0.04, so you were able to reject the null hypothesis at α = 5%. A Type I Error was committed. 2.
