A jury of size 12 is selectedat random from the population list of available jurors.Let X the number of Hispanics selected to be jurorsfor this jury.a. Is it reasonable to assume that X has a binomial dis-tribution? If so, identify the values of n and p. If not,explain why not.b. Find the probability that no Hispanic is selected.c. If no Hispanic is selected out of a sample of size 12,does this cast doubt on whether the sampling was trulyrandom? Explain.р.

The Ice Chalet offers dozens of different beginning iceskating classes. All of the class names are put into a bucket. The 5 P.M., Monday night, ages 8 to 12, beginning ice-skating class was picked. In that class were 66 girls and 14 boys. Suppose that we are interested in the true proportion of boys, ages 8 to 12, in all beginning ice-skating classes at the Ice Chalet. Assume that the children in the selected class are a random sample of the population. state the estimated distribution of x x~ (____,____)

On the following pages you are presented with five problems. Your job is to examine the output and discuss whether there is a statistically significant relationship between the two variables, the pattern or direction of the relationship if the relationship is significant, and the strength of the relationship if the relationship is significant. AS you discuss the strength of the relationship, you will rely on an appropriate measure of association from those that have been given. For that determination, you will need to appropriately determine the level of measurement of each of the variables being examined. Please use the Measures of Association Chart I provided to help you with your determination. You may write your responses on a separate document or next to the problems on this one.

A random sample of 7 oak trees from two forests was gathered. The results are shown below. Height of Trees (feet) Forest A Forest B 70 92 78 82 84 66 83 76 78 72 88 79 77 85 Based on the samples, which statement best compares the height of the oak trees in each forest? O The oak trees in Forest A are generally taller and have less variabillity than the oak trees in Forest B. The oak trees in Forest A are generally shorter and have less variabillity than the oak trees in Forest B. O The oak trees in Forest A are generally taller and have more variabillity than the oak trees in Forest B.

Suppose that a researcher is studying the wingspans of wild condors. To study this the researcher randomly selects 7 condors that live near the California Coast and 7 condors that live near the Grand Canyon for a total of 14 condors. The researcher measures the wingspan of each of these birds in inches and gets the following data. (Note: You may assume that there are about 400 condors in the wild) 94, 100, 102, 110, 115, 118, 119, 122, 123, 126, 128, 135, 136, 140 (All values in inches) (a) What sampling technique was used to collect this data? (b) Use this data to construct a 99% confidence interval for the average wingspan for California condors. Make sure to confirm all necessary conditions and interpret your interval. (Hint: This should be a 1-sample mean confidence interval) (c) Could you conclude that 99% of California condors will have wingspans inside the interval you found in (b)? Why or why not?
