na test of Ho:=50 against H:> 50, the sample data yielded the test statistic z = 1.92. Find and interpret the p-value for the test. Click the icon to view a table of standard normal values The p-value is p=D Round to three decimal places as needed.)

Interpret the decision in the context of the original claim.

The mean value in a dataset is 100, and the value of one standard deviation is 20. What is the value c a piece of data is 2.5 SDs above the mean? Type your answer...

The goal of the one-sample t-test is to: Group of answer choices describe the location of a score within a distribution compare the mean of a sample to the population mean. compare the means of two samples. compare the standard deviation of a sample to the standard deviation of the population.

Refer to the data set in the accompanying table. Assume that the paired sample data is a simple random sample and the differences have a distribution that is approximately normal. Use a significance level of 0.05 to test for a difference between the weights of discarded paper​ (in pounds) and weights of discarded plastic​ (in pounds).   LOADING... Click the icon to view the data. In this​ example, μd is the mean value of the differences d for the population of all pairs of​ data, where each individual difference d is defined as the weight of discarded paper minus the weight of discarded plastic for a household. What are the null and alternative hypotheses for the hypothesis​ test?     A. H0​: μd≠0 H1​: μd>0   B. H0​: μd=0 H1​: μd<0   C. H0​: μd=0 H1​: μd≠0   D.

Use Z-scores to determine which is a better relative golf score (remember that in golf, lower scores are better): Shooting a 75 in Tournament A where the mean score is 73 and the standard deviation is 3.3; or shooting a 76 in Tournament B where the mean score is 74 and the standard deviation is 3.5 .

Can you please help me answer and understand this problem?Thank you!
