For any problem where you use a preprogrammed TI function, you must writedown which function you use (complete name, not just something like"normal" because there are multiple normal functions), what values you enter(in order), and what the calculator produces. Round all probabilities to at leastfour decimal places.According to an article in the Journal of Anatomy (May, 2013), the ratio of thelength of a person's femur to the length of their tibia averages 1.23. Supposethis ratio is approximately normal with a mean of 1.23 and a standarddeviation of sigmaC. What proportion of people have a ratio between c1 and c2?e1f13.564 6.1875sigma0.031b11.25c11.2187c21.266d190beta4.95f214.058g125.7g270.9h133.47h258.06

Let X denote the ratio. Given that X follows N(mean = 1.23, SD = 0.031), then Z = (X - mean)/SD…

the mean weight of a group of boys is 145 lb, with a standard deviation of 5lb. if the weights are normally distributed, what percent of the boys from the group weigh between 142 lb and 152lb?
The U.S. Center for Disease Control reports that in year 1900, the mean life expectancy is 47.6 years for whites and 33 years for nonwhites. (Click here for reference data) Suppose a survey of randomly selected death records for white and nonwhite people born in 1900 from a certain county is conducted. Of the 110 whites surveyed, the mean life span was 48.2 years with a standard deviation of 11.2 years and of the 95 nonwhites, the mean life span was 39.3 years with a standard deviation of 16 years. Conduct a hypothesis test at the 0.05 level of significance to determine whether there was no difference in mean life spans in the county for whites and nonwhites in year 1900. Preliminary: Is it safe to assume thatnw≤5% of all white people born in 1900 andnnw≤5% of all nonwhite people born in 1900? No Yes Is nw≥30 and nnw≥30 ? No Yes Test the claim: Determine the null and alternative hypotheses. H0: μw μnw Ha: μw μnw Determine the test statistic. Round to four…

Humerus bones from the same species of animal have approximately the same length-to-width ratios. It is known that Species A has a mean ratio of 5.9. Suppose that 100 fossil humerus bones were unearthed at a site where Species A is known to have flourished. (We assume that all bones are from the same species.) The length-to-width ratios of these bones have a sample mean 5.6 and sample standard deviation 0.25. Can we conclude that the mean ratio of these bones is significantly smaller than those of Species A? Test with a 0.01 significance level. What is the standard error?
