For two inversely proportional quantities, what happens to one variable when the other increases? It decreases by the same factor 34. Arrange in the correct order the following four basic steps for finding the solution to a problem: compute, plan, evaluate, and analyze. analyze, plan, compute, evaluate 35. A student measure the mass of a sample as 9.67 g. Calculated the percentage error, given that the correct mass is 9.82 g. -1.5% 36.
Week 4 Quiz Name: The true and false questions are worth 2 point each. 1. The quick rule would say that in a bivariate scatter plot with 25 observations, a correlation of 0.45 is significantly different than zero (but just barely). [ X ] True [ ] False 2. The least squares regression line is obtained when the sum of the squared residuals is minimized.

TOPIC 8 Chi-Square goodness-of-fit test Problem 12.1 Use a chi-square goodness-of-fit to determine whether the observed frequencies are distributed the same as the expected frequencies (α = .05) Category | fo | fe | 1 | 53 | 68 | 2 | 37 | 42 | 3 | 32 | 33 | 4 | 28 | 22 | 5 | 18 | 10 | 6 | 15 | 8 | Step 1 Ho: The observed frequencies are distributed the same as the expected frequencies Ha: The observed frequencies are not distributed the same as the expected frequencies Step 2 df = k – m – 1 Step 3 α = 0.05 x 2 0.05, 5df = 11.0705 Step 4 Reject Ho if x 2 > 11.0705 Category | fo | fe | | 1 | 53 | 68 | | 2 | 37 | 42 | | 3 | 32 | 33 | | 4 | 28 | 22 | | 5 | 18 | 10 | | 6 | 15 | 8
Then for the unused equation and any of the other two equations repeat steps above. By this time you should have solved for two variables. Take the two variables you have solved for and put into any equation and solve for you remaining variable rather it be x, y, or z. Then the fourth step is to check put your tripled pair into all three equations and make sure they are correct. Do these steps have to be in a certain order?
Discuss how the Empirical Rule works and how it relates to the bell curve as illustrated in Figure 3.14 (a). Then, explain Chebyshevís Theorem and how it is different from the Empirical Rule. Give a specific example of a population with which the Empirical Rule might be most effective and one with which Chebyshevís Theorem might be most effective. Quiz 1. Due Day 6.
Average time of test administration ranges from 1 minute to 17 minutes. WIAT-III has been used in the identification of specific learning disabilities; WIAT-III may be used with other standard scores to conduct ability achievement discrepancy (AAD). Also through the use of the Scoring Assistant CD the Pattern of Strengths and Weakness (PSW) can be used to analyze specific learning disabilities (Pearson, 2009,
Make a decision whether to discard the null theory. To do this the Z score must be compared to the cutoff sample score which was found out in step 3. 14. Based on the information given for each of the following studies, decide whether to reject the null theory. For each, give (a) the Z-score cutoff (or cutoffs) on the comparison distribution at which the null theory should be turned down, (b) the Z score on the comparison distribution for the sample score, and (c) your conclusion.
