Solved in 2 steps with 2 images
- Looking at the tables for crosstabulation for Respondents Race, Highest Degree, and Respondents sex. How do we find out which one of these is the independent, dependent and or dummy variable? Also, how would you come up with an example for a Hypothesis for this? This is all one doccument. Table was too large. The first image is the top of the crosstab.New road signs are made with the intention of improving visibility for drivers. Highway safety engineer’s setup a test course that included both the old and new signs. Volunteers drove the course and rated the old and new signs in terms of visibility. a) Write the null and alternative hypotheses in words using “improved visibility” and “not improved visibility”.b) Describe a Type I error in the context of the problem.c) Describe a Type II error in the context of the problem.When performing a hypothesis test upon two dependent samples, the variable of interest is Group of answer choices a.the absolute value of the differences that exist between the matched-pair data. b.the differences that exist between the matched-pair data. c.the data that is the same in both samples. d.all of the combined data.
- 18. Question content area top Part 1 The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject H0 when the level of significance is (a) α=0.01, (b) α=0.05, and (c) α=0.10. P=0.0804 Question content area bottom Part 1 (a) Do you reject or fail to reject H0 at the 0.01 level of significance? A. Reject H0 because the P-value, 0.0804, is greater than α=0.01. B. Fail to reject H0 because the P-value, 0.0804, is less than α=0.01. C. Reject H0 because the P-value, 0.0804, is less than α=0.01. D. Fail to reject H0 because the P-value, 0.0804, is greater than α=0.01. Part 2 (b) Do you reject or fail to reject H0 at the 0.05 level of significance? A. Fail to reject H0 because the P-value, 0.0804, is less than α=0.05. B. Fail to reject H0 because the P-value, 0.0804, is greater than α=0.05. C. Reject H0 because the P-value, 0.0804, is less than…A medical researcher is interested in studying the effectiveness of 2 types of vaccines to treat diseases caused by new coronavirus. 40 samples were taken to measure the cure of the disease (hours) after the vaccine injection was taken. a) Write the null hypothesis b) Write the alternative hypothesis c) Test statistic d) Statistical table for Decision rule e) ConclusionWhen has a Type II error occurred?

- In Exercises, hypothesis tests are proposed. For each hypothesis test, a.determine the null hypothesis.b.determine the alternative hypothesis.c.classify the hypothesis test as two tailed, left tailed, or right tailed. Grey-Seal Nursing. Grey seals are one of several types of earless seals. The length of time that a female grey seal nurses her pup is studied by S. Twiss et al. in the article “Variation in Female Grey Seal (Halichoerus grypus) Reproductive Performance Correlates to Proactive-Reactive Behavioural Types” (PLOS ONE 7(11): e49598. doi:10.1371/journal.pone.0049598). The average lactation (nursing) period of all earless seals is 23 days. A hypothesis test is to be performed to decide whether the mean lactation period of grey seals differs from 23 days.PART B (b) Based on your answer to part (a), which of the following statements is true? ____ Since the p- valueis less than the significance level, the null hypothesis is rejected. _____ Since the p- valueis less than the significance level, the null hypothesis is not rejected. ____ Since the p- valueis greater than the significance level, the null hypothesis is rejected. ___ Since the p- valueis greater than the significance level, the null hypothesis is not rejected.In general terms, what does an alternative hypothesis (H1) say? Group of answer choices There is a treatment effect in the sample There is no treatment effect in the population There is a treatment effect in the population There is no treatment effect in the sample
- Problems pertain to the critical-value approach to hypothesis testing. State the general steps of the critical-value approach to hypothesis testing.When is a researcher at risk of making a Type II error? Group of answer choices: whenever H0 is rejected whenever H1 is rejected whenever H0 fails to be rejected The risk of a Type II error is independent of the decision from a hypothesis test.A plant in Alamo, TN, manufactures complex transformer components that must meet specific guidelines for safety. One such component is constructed to deliver 1,000 volts of electricity. A component creates a critical safety hazard if it absorbs humidity at a level above 3%. Any components that absorb too much humidity will be destroyed. A quality control inspector uses a random sample of components to conduct a hypothesis test with H0: The humidity level absorbed is 3%, and Ha: The humidity level absorbed is more than 3%. What is the consequence of a Type II error in this context? The company believes the humidity absorbed is more than 3% when in fact it is not. Correctly functioning components will be destroyed at great expense to the company. The company believes the voltage delivered is more than 1,000 volts, when in fact it is not more than 1,000 volts. Correctly functioning components will be destroyed at great expense to the company. The company believes the voltage delivered…
