Question 3>A comparison between species: Biologists wish to compare the prevalence of a genetic mutation acrosstwo species of Neema Toads. In a sample of 7 Neema Toads of Species I, 1.4% had the mutation while in asample of 14 Neema Toads of Species II, 1.9% showed the mutation. Is there significant evidence to suggesta difference in the prevalence of the mutation across the two species? Conduct a hypothesis test at asignificance level of a = 0.01.a) The hypotheses for this test are:O Ho: Pi - Pil = 0Ha: Pi-Pil ≈ 0O Ho: Pl - Pll = 0Ha: Pi - Pll < 0O Ho: Pl - Pil = 0Ha: Pi-Pil > 0O Ho: Pll = 0.014H₂: P = 0.014What is the test statistic for this test?test statistic =(Report answer accurate to 2 decimal places.)What is the p-value for this test?p-value =(Report answer accurate to 4 decimal places.)The decision reached isO Fail to reject HoO Reject Ho and accept HaAs such, the final conclusion is thatO The prevalence of the mutation is the same for both species.O There is not significant evidence to suggest a difference in the prevalence of the mutation across thetwo speciesO There is significant evidence that suggests no difference in the prevalence of the mutation across thetwo species.O There is significant evidence to suggest a difference between prevalence of the mutation across thetwo species

To test the fairness of law enforcement in its area, a local citizens' group wants to know whether women and men are unequally likely to get speeding tickets. Four hundred randomly selected adults were phoned and asked whether or not they had been cited for speeding in the last year. Using the results in the following table and a 0.05 level of significance, test the claim of the citizens' group. Let men be Population 1 and let women be Population 2. Speeding Tickets Ticketed Not Ticketed Men 26 191 Women 10 173 Copy Data Step 2 of 3: Compute the value of the test statistic. Round your answer to two decimal places.
A random sample of n1 = 157 people ages 16 to 19 were taken from the island of Oahu, Hawaii, and 12 were found to be high school dropouts. Another random sample of n2 = 129 people ages 16 to 19 were taken from Sweetwater County, Wyoming, and 6 were found to be high school dropouts. Do these data indicate that the population proportion of high school dropouts on Oahu is different (either way) from that of Sweetwater County? Use a 1% level of significance. (a) What is the level of significance? What is the value of the sample test statistic? (Test the difference p1 − p2. Do not use rounded values. Round your final answer to two decimal places.) (c) Find (or estimate) the P-value. (Round your answer to four decimal places.)
In a study comparing banks in two countries, a sample of 142 matched pairs of banks was formed. Each pair contained one bank from country x and one from country y. The pairings were made in such a way that the two members were as similar as possible in regard to such factors as size and age. The ratio of total loans outstanding to total assets was calculated for each of the banks. For this ratio, the sample mean difference (country x - country y) was 0.0579, and the sample standard deviation of the differences was 0.3086. Test, against a two-sided alternative, the null hypothesis that the two population means are equal. (Assume α = 0.01.) Click the icon to view the critical values of the Student's t distribution.

A poll was conducted to investigate opinions about global warming. The respondents who answered yes when asked if there is solid evidence that the earth is getting warmer were then asked to select a cause of global warming. The results are given in the accompanying data table. Use a 0.01 significance level to test the claim that the sex of the respondent is independent of the choice for the cause of global warming. Do men and women appear to agree, or is there a substantial difference?

In a study of red/green color blindness, 800 men and 2050 women are randomly selected and tested. Among the men, 68 have red/green color blindness. Among the women, 5 have red/green color blindness.

A random sample of 1100 potential voters was randomly divided into 2 groups. Group 1: 500 potential voters; no registration reminders sent; 248 registered to vote Group 2: 600 potential voters; registration reminders sent; 332 registered to vote Do these data support the claim that the proportion of voters who registered was greater in the group that received reminders than in the group that did not? Use a 1% level of significance.
