Step by step
Solved in 2 steps
- Need help writing a null hypothesis for the bivariate relationship shown in the SPSS output.From the resulted chi square value & degrees of freedom & the following table: calculate your p-value , and what is your hypothesis ?In this section, we used the statistic b1 as a basis for conducting a hypothesis test to decide whether a regression equation is useful for prediction. Identify two other statistics that can be used as a basis for such a test.
- Based on the SPSS output results given, you are required to explain the following: 1. Is the Null hypothesis can be rejected? Give your reason.2. Write down a summary of analysis (statistic equation) based on APA format.3. Describe (make an interpretation) of each result from the given analysis.I need help with these questions 1. What is the null hypothesis for this study? 2. what is the type 1 error associated with this data use the variable which cram or cramming, and study each week or both. 3. what is a type 2 error of this study?Assume that your sample(s) comes from a normally distributed population. Please show all work. State the null hypothesis and alternative hypothesis. State your decision in terms of the null hypothesis and the alpha level. State your results in standard APA format. What, if any relationship, exists between self-reported height for females and self-reported weight for the same female participants? Write a null and an alternative hypothesis for this research question (you may want to review Example 15.7 and Example 15.8 on page 508). Determine the relationship between the two measures for this sample (calculate r). Discuss and interpret the relation strength and direction indicated by this statistic. Test your hypothesis. Report your decision. Then, report your results using standard APA format (see page 509 in your text). Is there a relationship between self-reported major and self-reported IQ in the sample? Write a null and an alternative hypothesis for this research (you…
