The level of a pollutant in the river next to a chemical factory is monitored at regular intervals. Over the course of years, the level of the pollutant was determined by chemical analysis. In recent years, the company has made some changes in the factory where increases in the pollutant level can be observed. The environmental protection organization (EPA) wants convincing evidence that the level of the pollutant has not increased. By creating the relevant null and alternative hypotheses, I. type and II. describe type errors.
Identify the null and alternative hypothesis(in symbolic and sentence form), test statistic, P-value(or critical values), conclusion about the null hypothesis, and final conclusion that addresses the original claim(Don’t just say Reject the null hypothesis or fail to reject the null hypothesis). If you used the calculator, identify everything mentioned above in addition to which calculator functions and inputs for each field were used. 4. Test the claim that the mean age of the prison population in one city is less than 26 years. Sample data are summarized as n=25, Xbar=24.4, s=9.2. Use a significance level of a=0.05.

Test the claim that for the population of female college students, the mean weight is given by mu = 132 lb Sample data are summarized as n=20.x=137lb and s = 14.2 . How do you Use a significance level of alpha = 0.10 ?
When you fail to reject the null hypothesis for a two-way chi-square test, you can conclude that: Group of answer choices each possible value of the variable occurs with the same frequency. the distribution of the possible values of one variable is different for each of the possible values of the second variable. the distribution of the possible values of one variable is the same for each of the possible values of the second variable. the value of one variable is dependent upon the value of a second variable.
The value of the z-score in a hypothesis test is influenced by a variety of factors. Assuming that all other variables are held constant, explain how the value of z is influenced by each of the following: Increasing the difference between the sample mean and the original population mean. Increasing the population standard deviation. Increasing the number of scores in the sample.

Test the hypothesis that the population mean age of all students in MAT125 is less than 26 years old. Test at the 0.05 level of significance
1. The average wage of Filipino workers in the Philippines is significantly below Php 250. It is Null hypothesis or Alternative Hypothesis 2. Sleep-deprived students have lower performance in the mathematical learning ability test than those with 8 hours of sleep. It is Null hypothesis or Alternative Hypothesis
In a statistical test, we have a choice of a left-tailed test, a right-tailed test, or a two-tailed test. Is it the null hypothesis or the alternate hypothesis that determines which type of test is used? Select the correct answer: The alternative hypothesis because it specifies what the level of significance of the test will be. The alternative hypothesis because it specifies the region of interest for the parameter in question. The null hypothesis because it specifies the region of interest for the parameter in question. The null hypothesis because it specifies what the level of significance of the test will be.
A recent study at a college classified a group of 200 students according to whether they attended their classes and whether they passed a particular exam. 93 students attended their classes and passed the exam, 7 students didn't attend their classes but passed the exam, and 60 students didn't attend their classes and failed in the exam. The researcher in the study computed the test statistics. What hypothesis can be tested using the test statistics above And Compute the test statistics appearing above and test the hypothesis of interest . Interpret theresults.
Formulate the indicated conclusion in nontechnical terms. Be sure to address the original claim. An entomologist writes an article in a scientific journal which claims that fewer than 14 in ten thousand male fireflies are unable to produce light due to a genetic mutation. Assuming that a hypothesis test of the claim has been conducted and that the conclusion is to reject the null hypothesis, state the conclusion in nontechnical terms. A. There is sufficient evidence to support the claim that the true proportion is less than 14 in ten thousand. B. There is not sufficient evidence to support the claim that the true proportion is greater than 14 in ten thousand. C. There is sufficient evidence to support the claim that the true proportion is greater than 14 in ten thousand. D. There is not sufficient evidence to support the claim that the true proportion is less than 14 in ten thousand.
