Random samples of 110 homes in Kingston, Ontario (₁) and 100 homes in Owen Sound, Ontario (₂) wereselected. Each home was examined for the presence of asbestos, and it was found that 20 homes in OwenSound and 35 homes in Kingston had some presence of asbestos.We would like to test whether the proportion of homes with asbestos in Kingston (p₁) is greater than theproportion of homes in Owen Sound with asbestos (p₂). What test statistic should we use? Here, we willdenote by p the proportion of homes with asbestos in Kingston and Owen Sound combined.Select one:a. Z =O c.P₁-P₂√p(1-p)(1/n₁+1/1₂)O b. x = Σ (Ex-OK)²i=1Ekx, where Ek is the expected number of observations, and Ok is the actualnumber of observations, in the cells of the contingency table corresponding to this problem.N(0, 1)Z =N (0, 1)P1-P₂√P₁(1-P₁)/n₁+p₂(1-P₂)/n₂)

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? (b)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.)
After the measles outbreak, the barangay captain of Big Rock wanted to assess the satisfaction of the residents to his actions during the outbreak. He then obtained a random sample of 5 residents per block (Block 1 to Block 5) and asked them their satisfaction (1 – very dissatisfied, 2- dissatisfied, 3- satisfied, 4- very satisfied). He wanted to know if the satisfaction of his residents differs across blocks. i. True or False: We should test the normality of responses per blocks before we proceed with the test of hypothesis on comparing these responses across blocks. ii. The appropriate alternative hypothesis in symbols is? a) At least one µi # µj, for izj, i,j=1,2,3,4,5 b) At least one Mdi + Mdj, for i#j, i,j=1,2,3,4,5 c ) μ1 μ2-μ3-μ4 μ5 d) Md1= Md2 = Md3 = Md4 = Md5 iii. Suppose the p-value of appropriate test is 0.0013, at 5% level of significance, we have evidence to say that at least one block has a different average a) Insufficient; measles outbreak b) Sufficient; measles…
Public relation companies conducted two surveys about deodorants. The first survey asked a random sample of 500 men about their use of a natural deodorant. A second survey asked the same questions to a random sample of 550 women. In these two studies, 68% of men and 44% of women stated they were dissatisfied with the effectiveness of natural deodorants. Use these results to answer the following questions about the proportion of men and women's satisfaction with natural deoderants. (Round to the nearest whole person as needed). What is the difference between the proportion of men and women? _____ (write as a decimal) The standard error for these two samples is ______ . (round to the nearest hundredth) Using a 99% confidence level, the lower limit is _____ and the upper limit is _____
A random sample of n1 = 148 people ages 16 to 19 were taken from the island of Oahu, Hawaii, and 14 were found to be high school dropouts. Another random sample of n2 = 125 people ages 16 to 19 were taken from Sweetwater County, Wyoming, and 5 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.

Acne is a common skin disease that affects most adolescents and can continue into adulthood. A study compared the effectiveness of three acne treatments and a placebo, all in gel form, applied twice daily for 12 weeks. The study's 517 teenage volunteers were randomly assigned to one of the four treatments. Success was assessed as clear or almost clear skin at the end of the 12 week period. The results of the study can be seen in the table below. Using the appropriate statistical test, determine if there is significant evidence that the four treatments perform differently. If so, how do they compare.

Is there a statistically significant difference between men and women's satisfaction with natural deodorants? A Yes, the proportion of men that are satisfied with natural deodorants is significantly less than the proportion of women that are satisfied with natural deodorants because both the lower limit and the upper limit of the confidence interval are positive values. B Yes, the proportion of men that are satisfied with natural…

In the twentieth century, it was a common practice in Southern California for houses to be built with pools in the backyard. For new homes, however, that practice may be changing, possibly as a measure to help reduce climate change. A recent study examined a random sample of 140 houses built in Southern California in the twentieth century and an independent, random sample of 81 new houses built in Southern California. The sample of twentieth century houses contained 61 houses with pools, and the sample of new houses contained 24 houses with pools.Based on this survey, can we conclude, at the 0.05 level of significance, that the proportion p1 of all Southern California twentieth century houses that were built with pools is greater than the proportion p2of all new Southern California houses that were built with pools?Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the…
