Wisconsin State government is attempting to improve the productivity of its workforce by trying to reduce the number of productive hours lost due to clerical mistakes. Wisconsin government plans to install new software to help manage productivity and reduce number of hours lost. To test the effectiveness of this software, a random sample of 50 departments across the state have been selected. For each of the 50 departments, number of hours lost in productivity is recorded in the month before and the month after the installation of the new software. For each department in the sample percentage change was calculated and then averaged across all the departments. Based on this sample, the average percentage change was calculated to be -1.20%. Assume that the population standard deviation is o = 6. Can it be inferred at the 10% significance level that the new software is effective at reducing loss of productive hours? (Hint: here u = the mean percentage change; and sample mean is -1.2)

Self-reported injuries among left- and right-handed people were compared i n a survey of 1896 college students i n British Columbia, Canada. Of the 18 O left- handed students, 93 reported at least one injury. In the same period, 619 of the 1716 right-handed students repor ted at least one injury.

Q3 Test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, and then state the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Among 2125 passengers cars in a particular region, 229 had only rear license plates. Among 326 commercial trucks, 47 had only rear license plates. A reasonable hypothesis is that commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passengers cars. Use a 0.01 significance level to test that hypothesis. A. Identity the nulls and alternative hypotheses B. Identify the test statistic ( round to two decimal places as needed) C. Identify the p- values (round to two decimal places as needed ? State the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. A. Fail to reject Ho. There is not sufficient evidence to support the claim that commercial trucks owners…

What is F test of the null hypothesis?
find p value and its meaning please A survey of 1000 adults from a certain region asked, "If purchasing a used car made certain upgrades or features more affordable, what would be your preferred luxury upgrade?" The results indicated that 58% of the females and 51% of the males answered window tinting. The sample sizes of males and females were not provided. Suppose that of 600 females, 348 reported window tinting as their preferred luxury upgrade of choice, while of 400 males, 204 reported window tinting as their preferred luxury upgrade of choice. Complete parts (a) through (d) below. a. Is there evidence of a difference between males and females in the proportion who said they prefer window tinting as a luxury upgrade at the 0.05 level of significance? State the null and alternative hypotheses, where π1 is the population proportion of females who said they prefer window tinting as a luxury upgrade and π2 is the population proportion of males who said…
HW Help, Thank You!!!
When we test the hypothesis, can you explain the difference between one and of two-sample tests? How would I know if I can reject this null hypothesis? Can you give an example of the one and two-sample tests? Why does the t-value have different formulas in a two-sample test?
What is the conclusion? What is your conclusion? -There is no evidence to suggest a difference. -There is a difference in newborns' APGAR score based on whether the mother smoked or not. -Newborns whose mothers didn't smoke have higher APGAR score than newborns whose mother did smoke. -Newborns whose mothers didn't smoke have lower APGAR score than newborns whose mother did smoke.
A p-value smaller than the significance level, a means.... We should reject the Null Hypothesis O We should not reject the Null Hypothesis
