In 2003​, a reproductive clinic reported 41 live births to 157 women under the age of​ 38, but only 6 live births for 79 clients aged 38 and older. Is there evidence of a difference in the effectiveness of the​ clinic's methods for older​ women? ​a) Test an appropriate hypothesis and state your conclusion.​ (Use the pooled sample proportion when checking the​ success/failure condition.) ​b) If you concluded there was a​ difference, estimate that difference with a 95​% confidence interval and interpret your interval in context.

In 2001​, a reproductive clinic reported 43 live births to 169 women under the age of​ 38, but only 9 live births for 75 clients aged 38 and older. Is there evidence of a difference in the effectiveness of the​ clinic's methods for older​ women? Determine the test statistic, the p-value, and if there is a difference, estimate the difference p1-p2 with a 95% confidence interval.

women who reported an earlier age at menarche were more likely to be heavier at age 7 years (average weight = 24.7 kg) compared with those who reported a later age at menarche (average weight = 23.2 kg) (P = 0.01). The correlation between weight at age 7 years and age at menarche was -0.17 (P = 0.009). Q: The -0.17 value is for what? how to find it and why it is important to mention?

In December 2001, 38% of adults with children under the age of 18 reported that their family ate dinner together seven nights a week. In a recent poll, 403 of 1122 adults with children under the age of 18 reported that their family ate dinner together seven nights a week. The researcher wishes to estimate the current proportion of families with children under the age of 18 who eat dinner together seven nights a week with 95% confidence. a. What...

a) In the 1999-2000 NHANES report, the reported cancer rate for women subjects age 65 and older is 14%. Using this estimate as the true percentage of all females ages 65and over who have been told by a health care provider that they have cancer, find the probability that if 210 women are selected at random from the population, more than 20% will have been told they have cancer. b) In the same report, the cancer rate for men ages...
