Over the years 72 percent of females and 67 percent of males pass math and science classes as students. We would like to understand if females pass math science more readily. We took a sample of 190 females and 370 male students from the country at random. Do females pass math and science more readily? (Assume significance level of level. -Calculate the standard error for the above context -Calculate the 99% confidence interval for the difference in the true proportion of male and female students who pass math and science. Interpret the confidence interval and determine if there is a significant difference between the two groups.

A random sample of 858 births in a state included 429 boys. Construct a 95% confidence interval estimate of the proportion of boys in all births. It is believed that among all births, the proportion of boys is 0.507. Do these sample results provide strong evidence against that belief? Question content area bottom Part 1 Construct a 95% confidence interval estimate of the proportion of boys in all births. enter your response here<p<enter your response here (Round to three decimal places as needed.) Part 2 Do these sample results provide strong evidence against that belief? A. There is strong evidence against 0.507 as the value of the proportion of boys in all births because 0.507 is not contained within the 95% confidence interval. B. There is not strong evidence against 0.507 as the value of the proportion of boys in all births because 0.507 is not contained within the 95% confidence interval. C. There is strong evidence against…
