(two large sample populations hypothesis test)

A study examined the relations of species diversity in a cropland against a wetland.

                                                Cropland                              Wetland

Mean                                       14.06                                   15.36

SD                                            4.53                                   6.25
Sample Size                            126                                      98

Is there evidence at a 98% confidence level that the wetland has more species diversity than the cropland?

A correlational study examined the relationship between a large group of students' overall achievement and their level of self-confidence. The results were reported as statistically significant (r = .17, p. = .01). With what should you be concerned? a. The theoretical importance of this study b. The lack of statistical significance of the results c. The lack of practical significance of the results d. The sample size

A study of the pay of corporate chief executive officers (CEOs) examined the increase in cash compensation of the CEOs of 97 companies, adjusted for inflation, in a recent year. The mean increase in real compensation was x = 6.8%, and the standard deviation of the increases was s = 45%. Is this good evidence that the mean real compensation μ of all CEOs increased that year? Ho: μ = 0 (no increase) Ha: μ > 0 (an increase) Because...

Suppose you are going to test the hypothesis that two populations have the same mean. You find sample averages of 6 and 7.5 and sample 1 has a standard deviation of 16 and sample 2 has a standard deviation of 15 and both samples have 32 observations. In this case the test statistic follows the t distribution with 61 degrees of freedom. True or False: you reject the null hypothesis at the .01 level of significance. true or false

Two different simple random samples are drawn from two different populations. The first sample consists of 20 people with 10 having a common attribute. The second sample consists of 2200 people with 1595 of them having the same common attribute. Compare the results from a hypothesis test of p1 = p2 ​(with a 0.01 significance​ level) and a 99​% confidence interval estimate of p1 - p2. 1. Identify the test statistic ____ (round to 2 decimal places) 2. Identify the...

1.) One tailed test or two tailed test? You are performing a hypothesis test for the mean sample weight of your fellow Intro to Statistics students. For your null hypothesis , the hypothesized mean weight for the entire campus student body is 165. You have no reason to know for your alternative hypothesis whether the actual mean weight for the entire student campus body is more or less than 165. So you decide to make your alternative hypothesis as not...

HW #42 #4 You are conducting a study to see if the proportion of men over 50 who regularly have their prostate examined is significantly more than 0.85. You use a significance level of α=0.001α=0.001.       H0:p=0.85H0:p=0.85       HA:p>0.85HA:p>0.85 You obtain a sample of size n=470n=470 in which there are 425 successes. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to four...
