A researcher surveys 50 individuals in the North Ward of Thunder Bay, and 40 in the South Ward, and finds that 40% of the North Ward residents had visited the Port Arthur Waterfront in the last year, while only 30% of South Ward residents had. Is there enough evidence to conclude that the rates of use in the two wards differ? Use a two-tailed test with a = 0 10

Below is a set of exam 1 scores from our Statistics class. 7 of the scores come from females, and 7 come from males. Test the hypothesis that males and females scored differently on our first exam, using an (alpha level of .05.) Male Female 75 99 92 75 85 44 90 99 46 95 61 90 70 100 What is the apporpriate test, null hypothesis, alternative hypothesis, critical value(s), obtained statistic, make a decision what does this mean?

Test the claim that the proportion of men who own dogs is smaller than the proportion of women who own dogs at the .005 significance level. Based on a sample of 80 men, 40% owned dogsBased on a sample of 80 women, 60% owned dogs Critical Value = Test Statistic = Based on this do we reject the null hypothesis or fail to reject the null hypothesis?

Hypothesis Test is conjectured that the proportion of all people who went trick-or-treating who also had a pumpkin carved into a jack-o'-lantern at their home is 0.62. Of interest is to test this claim versus the alternative that the proportion of all people who went trick-or-treating who also had a pumpkin carved into a jack-o'-lantern at their home is less than 0.62. A simple random sample of 270 people who went trick-or-treating is selected, and 162 of them also had a pumpkin carved into a jack-o'-lantern at their home (and the other 108 did not). If appropriate, use this information to test if the proportion of all people who went trick-or-treating who also had a pumpkin carved into a jack-o'-lantern at their home is less than 0.62 at the a = .10 level of significance. Which of the following provides both the correct null and the correct alternative hypothesis for this situation? НО: п = 0.62 Ha: π 0.62, Ha::n 0.58 Ha:: π < 0.62

Please help!  This is the part 'c' since it got cut off in the picture: (c)Based on your answer to part (b), choose what can be concluded, at the 0.10 level of significance, about the claim made by the management.       Since the p-value is less than (or equal to) the level of significance, the null hypothesis is rejected. So, there is enough evidence to support the claim that the mean customer rating is not equal to 75 .   Since the p-value is less than (or equal to) the level of significance, the null hypothesis is not rejected. So, there is not enough evidence to support the claim that the mean customer rating is not equal to 75 .   Since the p-value is greater than the level of significance, the null hypothesis is rejected. So, there is enough evidence to support the claim that the mean customer rating is not equal to 75 .   Since the p-value is greater than the level of significance, the null hypothesis is not rejected. So, there is not enough evidence to…

You are testing the claim that the proportion of men who own cats is larger than the proportion of women who own cats. You sample 190 men, and 113 own cats. You sample 50 women, and 24 own cats.

NT #2 You wish to test if the proportion of adults in a small town who are fully vaccinated differs from 55%. You select a random sample of 258 adults in this town and find that 120 of them are fully vaccinated. Set up an appropriate hypothesis test, calculate the p-value and state your conclusion. Use a significance level of a = .01.

An education researcher claims that at most 3% of working college students are employed as teachers or teaching assistants. In a random sample of 300 working college students, 5% are employed as teachers or teaching assistants. At a = 0.05, is there enough evidence to reject the researcher's claim? (c) find the standardized test statistic z.

You are conducting a study to see if the probability of a true negative on a test for a certain cancer is significantly different from 0.53. You use a significance level of a = 0.02. Ho:p = 0.53 H1:p + 0.53 You obtain a sample of size n = 577 in which there are 341 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 decimal places.) p-value = The p-value is...
