People spend an average of $11 on entertainment. You believe that for people who live in Arizona, this number is significantly lower. To test, you randomly sampled n=100 Arizona residents and asked them how much they spend on entertainment. The sample average of these respondents was $10.74 with a sample standard deviation of $1.2. If you want to test the null hypothesis that H0: u=11 vs Ha: u<11, what is the value of the test statistic?

Perform the following hypothesis test: HO: µ = 10 H1: µ 10 The sample mean is 9.55, population standard deviation of 1.5 and a sample size of 51. Use a 5% significance level. What is the value of the test statistic? (Give your answer rounded to 2 decimals) (Be careful to make sure your + or - sign is correct)What is the p-value for this problem?
You wish to determine if there is a linear correlation between the two variables at a significance level of α=0.01α=0.01. You have the following bivariate data set.

Researchers compared two groups of competitive rowers: a group of skilled rowers and a group of novices. The researchers measured the angular velocity of each subject’s right knee, which describes the rate at which the knee joint opens as the legs push the body back on the sliding seat. The sample size ?, the sample mean, and the sample standard deviation for the two groups are given below. Group N x̄ s Skilled 16 4.2 0.6 Novice 16 3.2 0.8 Construct the 99% confidence interval for the difference between the groups. How does this confidence interval relate to the conclusion of your test?
You wish to determine if there is a linear correlation between the two variables at a significance level of a = 0.01. You have the following bivariate data set.

O There is insufficient sample evidence to support the claim the there is a correlation between the two variables. There is sufficient sample evidence to support the claim that there is a statistically significant correlation between the two variables.
I’m stuck on how to do this problem for stats.
To answer the following questions, perform a x? test on the data. Be sure to show all your work and include the following information in your answer: x² value; number of degrees of freedom; P; whether the deviation is significant or nonsignificant; do you accept or reject the hypothesis. For each of the situations below, determine the degrees of freedom associated with the X² statistic and decide whether or not the observed x? value warrants acceptance or rejection of the hypothesized genetic ratio. 1. hypothesized ratio a. 3:1 7.0 b. 1:2:1 7.0 C. 1:1:1:1 7.0 d. 9:3:3:1 5.0 Degrees of Freedom Probability (P) Accept / Reject a. b.
