if the zobt is greater than the z critical, what can i assume within this data set?
A.Since zobt > zcrit, we have proven the alternative hypothesis.
B.Since zobt > zcrit, we fail to reject the null hypothesis.
C.since zobt > zcrit, we reject the null hypothesis.
(Q) If the zobt is greater than the z critical, what can i assume within this data set?
Answer:
If the zobt is greater than the z critical, we reject the null hypothesis.
Answer: since zobt > zcrit, we reject the null hypothesis.
Therefore the "option-C" is the correct answer.

Given the following null and alternative hypotheses, the test statistic from the sample data is z=1.875z=1.875. If the significance level of 0.05 which results in a critical value of 1.645, what is the conclusion as it relates to the null hypothesis? H0:p=0.22 H1:p>0.22 Fail to reject the alternative hypothesis Reject the null hypothesis Fail to reject the null hypothesis Support the null hypothesis
assume that the data has a normal distribution and the number of observations is greater than fifty Find the critical z value to test the null hypothesis, alpha = 0.10 for a two-tailed test.
1. Regarding a two-tailed z-test with an alpha of 0.05, we would need a Zobt with an absolute value less than 1.96 in order to reject the null hypothesis. True or False? 2. What happens to the probability of committing a Type I error if the level of significance is changed from α = 0.05 to α = 0.01? A. It increases B. It decreases C. It stays the same D. Cannot determine 3. Given a Zobt of -1.99 ,...
Assume that the data has a normal distribution and the number of observations is greater than fifty. Find the critical z value used to test a null hypothesis. Round to two decimal places. α = 0.07; alternate hypothesis H 1 is μ ≠ 3.24 ± __________

Examine the R output below. > t.test(x, mu = 0, alternative = "greater") One Sample t-test data: x t = -0.11931, df = 99, p-value = 0.5474 alternative hypothesis: true mean is greater than 0 95 percent confidence interval: -0.1939536 Inf sample estimates: mean of x -0.01300261 What would be the conclusion for the t-test? Reject the null hypothesis Reject the alternative hypothesis Fail to reject the null hypothesis Fail to reject the alternative hypothesis
1.) A recent sample of 1250 teenagers found that 83% hope to be married within the next 10 years. Does this evidence show that the percentage of proportion of teenagers who hope to be married is significantly less than 85%? Test using alpha=0.05. Shade the curve using the critical value. Also, graph the test statistic on the curve. a. Claim: b. Null Hypothesis c. Alternative Hypothesis: d. Test to be used? e. Test statistic: f. What is the p-value? g....
I spefically need to see how
the test statistic and critical value is calculated.
Test the claim that the proportion of men who own cats is significantly different than 80% at the 0.02 significance level. The null and alternative hypothesis would be: The test is: left-tailed right-tailed two-tailed Based on a sample of 55 people, 78% owned cats The test statistic is: (to 2 decimals) The positive critical value is: (to 2 decimals) Based on this we: Reject the null...
