Previously, 5% of mothers smoked more than 21 cigarettes during their pregnancy. An obstetrician believes that the percentage of mothers who smoke 21 cigarettes or more is less than 5% today. She randomly selects 155 pregnant mothers and finds that 6 of them smoked 21 or more cigarettes during pregnancy. Test the researcher's statement at the a = 0.1 level of significance. What are the null and alternative hypotheses? < 0.05 = 0.05 versus H,: p (Type integers or decimals. Do not round.) Но: р Because npo (1- Po) =|| V10, the normal model (Round to one decimal place as needed.) V be used to approximate the P-value.

Only 17% of registered voters voted in the last election. Will voter participation decline for the upcoming election? Of the 391 randomly selected registered voters surveyed, 47 of them will vote in the upcoming election. What can be concluded at the αα= 0.01 level of significance?For this study, we should use The null and alternative hypotheses would be: H0:H0:(please enter a decimal) H1:H1:(Please enter a decimal)The test statistic = (please show your answer to 3 decimal places.)The p-value = (Please show your answer to 4 decimal places.)The p-value is ααBased on this, we should the null hypothesis.Thus, the final conclusion is that ... The data suggest the populaton proportion is significantly lower than 17% at αα= 0.01, so there is statistically significant evidence to conclude that the the percentage of all registered voters who will vote in the upcoming election will be lower than 17%.The data suggest the population proportion is not significantly lower than 17% at αα= 0.01, so…

Let x1, X2, ..., Xn be a random sample from a normal population with unknown mean u and an unknown variance o?. At a given significance level a, derive the generalized likelihood ratio test for Ho : o 5. versus Completely specify the test when a = population: 0.05 and n = 26. Does the power function of the test depend on the mean of the The following `answers" have been proposed. %3B 26 (a) For a = 0.05 and n = 26 the test rejects Ho when E(X; – X„)² > 941.25. The power function of the test indirectly depends on the population mean u via = 7. (b) For a = 0.05 and n = 26 the test rejects Ho when E(X; – Xn)² > 941.25. The power function of the test does not depend on the population mean µ. (c) For a = 26 ,26 0.05 and n = 26 the test rejects Ho when E(X; – Xn)² > 188.25. The power function of the test does not depend on the population mean µ. (d) For a = 0.05 and n = 26 the test rejects Ho when E(X; – X„)² > 188.25.

14% of all Americans suffer from sleep apnea. A researcher suspects that a different percentage of those who live in the inner city have sleep apnea. Of the 325 people from the inner city surveyed, 62 of them suffered from sleep apnea. What can be concluded at the level of significance of αα = 0.05? Round numerical answers to 3 decimal places For this study, we should use     The null and alternative hypotheses would be:     Ho:            (please enter a decimal)    H1:            (Please enter a decimal) The test statistic     =  (please show your answer to 3 decimal places.) The p-value =  (Please show your answer to 4 decimal places.) The p-value is     αα Based on this, we should      the null hypothesis. Thus, the final conclusion is that ... The data suggest the population proportion is not significantly different from 14% at αα = 0.05, so there is not sufficient evidence to conclude that the population proportion of inner city residents who have sleep apnea is different…

Previously, 5% of mothers smoked more than 21 cigarettes during their pregnancy. An obstetrician believes that the percentage of mothers who smoke 21 cigarettes or more is less than 5% today. She randomly selects 150 pregnant mothers and finds that 5 of them smoked 21 or more cigarettes during pregnancy. Test the researcher's statement at the a = 0.05 level of significance. What are the null and alternative hypotheses? = 0.05 versus H,: p < 0.05 Ho: P (Type integers or decimals. Do not round.) Because npo (1- Po) = [ (Round to one decimal place as needed.) V 10, the normal model V be used to approximate the P-value.

The study shows that for lung cancer, less than 5% of patients were cured in Denmark and Poland, whereas more than 10% of patients were cured in Spain. To test the claim regarding proportion of cured cancer patients in Spain, a random sample of 500 patients yielded 39 who were cured. Perform the appropriate test of hypothesis to write your conclusion. Hо: р = 0.10 versus Ha:p > 0.10. Reject Ho Но: р 3 = 0.10 versus Ha:p 0.10. Accept Ho
