(a) What is power? (b) Why do researchers wantto maximize power? (c) Is power more importantwhen we reject or when we retain H? Why?(d) Why is a one-tailed test more powerful thana two-tailed test? 14. We ask if visual memory ability for a sample of 25 artmajors (X= 49) is better than that for a populationof engineering majors (u = 45 and ax= 14). Higherscores indicate a better memory. (a) What is the pre-dicted relationship here? (b) Is this a one- or a two-tailed test? (c) In words, state Ho and H. (d) ComputeZab: (e) What is z? (f) What do you conclude aboutdifferences in visual memory ability? (g) Report yourresults using the correct format.crit

I am a little unclear on how to obtain the p value given the z value and how to determine the tail tests. Can you go a bit more in depth on that part?
The degrees of freedom is critical to computing the p-value for the chi-square goodness of fit. We will discuss the p-value in the next lab. The degrees of freedom for the Chi-Square goodness of fit is equal to (the number of non-zero rows in the table) - 1. The number of non-zero rows is the number of expected values that are non-zero. For example: Phenotype ... Expected ... Disease ... 234 ... Wild-type ... 6743 ... has two rows where the Expected value is non-zero. So the degrees of freedom is 2-1 = 1. Another example: Phenotype ... Expected ... Disease ... 2374 ... Wild-type ... 0 ... has one row where the Expected value is non-zero. So the degrees of freedom is 1-1 = 0. With 0 degrees of freedom, the chi-square test cannot be calculated. A third example (sex-linked): Phenotype ... Expected ... Disease-Male ... 2374 ... Disease-Female ... 9456 Wild-type-Male ... 1001 ... Wild-type-Female ... 235 ... has four rows where the Expected values are…

A random sample of 42 earthquakes that have occurred between January 2015 and September 2017 was selected and for each earthquake the magnitude of the earthquake and the number of people killed was recorded. The data appear in the scatterplot below. 400 350 300 250 200 150 100 50 0 3 -50 4 5 6 7 8 9 10 -100 -150 Magnitude of Earthquake 8 Consider the scatterplot above question 2.

Question(14): A researcher wanted to know whether children who live in two different neighbourhood (Willowdale and Forresthill) got different amount of excerise. Children were randomly selected from the two neighbourhoods (40 in each). and filled out the daily activity report to measure their excerise. The number of minutes of excerise were tallied and recorded. The The researcher then conducted an independent sample t test using MS-EXCELL. The result are shown in the image below. Inspect the MS- EXCELL output.Did the researcher conduct their t test assuming equal variance.? Write out Step 5 by including both the formal answer and the conclusion. The five steps are: Step 1:State the hypotheses and identify the claim. Step 2: Compute the test value Step 3: Compute the critical value. Step 4:Make the decision (reject or not reject) Step 5:Summaize the results. Note: you only need to submit step 5, and round snswer to decimal places MS-EXCELL output:…
