Do all hypothesis testing steps here:

Presented below are scores on two tests. The teacher wants to know if there is a relationship between the two tests. The following data is from a group of participants for their performance on a test of perceptual skills and on a test of reading ability.

A.Also make a scatterplot (by hand) for this data. (this is your hint it's a Pearson’s R)

B.Calculate the regression equation for predicting scores on the Y’(Reading test) variable.

C.Predict Y for X = 17

D.Predict Y for X = 20

(X)Perceptual Test: 15 14 10 9 8 8 7 6 4 2

(Y)Reading Test: 4 6 4 8 7 8 10 9 14 12

Remember these are paired up so the N=10

For all hypothesis tests, be sure to include information for all 7 steps. For any two-sample or paired t-tests that you perform, in Step 6, show the decision rule based on BOTH the critical value and the p-value. Use the online app for the t-distribution to compute your p-values. The Bayley Scales of Infant Development yield scores on two indices – the Psychomotor Development Index (PDI) and the Mental Development Index (MDI) – that can be used to assess a...

For Questions 1 and 2, include all Steps of Hypothesis Testing listed below in bold. For each problem, use the p-value from SPSS to determine whether to reject or not reject the null hypothesis and don’t forget to indicate your conclusion about whether there is a significant difference. 1)State your hypotheses: H0 and H1 2)Select the appropriate statistical test 3)Indicate whether test is directional or non-directional 4)Specify a, N, and df (if appropriate) 5)Do your calculations 6)Determine critical value(s) for...

Do all hypothesis testing steps and find the correlation coefficient for the following data to determine if there is a significant correlation between the results of IQ test and Test A scores. (A higher score on either tests = a “better” score”) A.Also make a scatterplot (by hand) for this data. (IQ is X and Test Score is Y, also begin at 90 for X and 30 for Y) B.Calculate the regression equation for predicting scores on the Y’(Reading test)...

What are the steps in hypothesis testing? What is the goal of hypothesis testing? What are null and alternative hypotheses? In §9.2 the concepts of Type I and Type II errors are introduced.Consider the situation where a husband and wife go to the doctor’s office to each get some tests run and the doctor accidentally mixes up their charts. The doctor comes into the exam room with the results of the tests and declares that the wife is NOT pregnant but...

Include: all hypothesis tests with all four steps all Confidence Intervals with all output as well as the CI itself' all calculator functions used An experiment was done to see whether open-book tests make a difference. A calculus class of 48 students agreed to be randomly assigned by the draw of cards to take a quiz either by open-notes or closed-notes. The quiz consisted of 30 integration problems of varying difficulty. Students were to do as many as possible in...

Remember to SHOW ALL YOUR WORK, and INCLUDE ALL STEPS for hypothesis tests. 1. A sociologist is investigating the relationship between life satisfaction and sociability. For a sample of 16 individuals, the following data is obtained: SP = 5.14 Sociability: M=10.62 SS=5.12 Life Satisfaction: M=9.53 SS=7.24 a. Compute the correlation between sociability and life satisfaction. b. What can be said about the nature of the relationship between these two variables? c. Compute the coefficient of determination. What does this value...

Consider the seven steps of hypothesis testing. The final step in the hypothesis-testing process involves deciding whether to reject the null hypothesis. Assuming thenull hypothesis is not rejected, what is the difference between accepting the null hypothesis and failing to reject it? Explain your reasoning.
