A coffee company received 36 3/4 kilograms of coffee beans at $260 per kilogram. Sales for the next five days were as follows: 3 5/8 kilograms, 4 3/4 kilograms, 7 2/3 kilograms, 5 1/2 kilograms, and 6 3/8 kilograms. What was the value of inventory at the end of Day 5?

A Survey was conducted of newlyweds in a country who have a spouse of a different race or ethnicity from their own. The survey included random samples of 1000 newtyweds in Ethnicity A and 1000 newlyweds in Ethnicity B. In the survey, 13% of respondents of a different race or ethnicity from their own is less than the proportion of newlyweds in Ethnicity B that have a spouse of a different race or ethnicity from their own? Ethnicity A and 24% of respondents in Ethnicity B had a spouse of a different race or ethnicity from their own. At a = 0.01, is there evidence to support the claim that the proportion of newlyweds in Ethnicity A who have a spouse Let p, represent the proportion of newlyweds in Ethnicity A who have a spouse of a different race or ethnicity from their own. Let p, represent the proportion of newlyweds in Ethnicity B that have a spouse of a different race or ethnicity from their own. State the null and alternative hypotheses. YA.

Two human traits controlled by a single gene are the ability to roll one’s tongue and whether one’s ear lobes are free or attached to the neck. Genetic theory says that people will have neither one, one, or both of these traits in the ratio 1:3:3:9 (1/16—attached, noncurling; 3/16—attached, curling; 3/16—free, noncurling; 9/16— free, curling). A biology class of 122 students collected these data: ear lobes, tongue observed count attached, noncurling 10 attached, curling 22 free, noncurling 31 free, curling 59 Are these data consistent with the genetic theory? State appropriate hypotheses and identify the appropriate test. Assuming these data are independent, how do you know if this sample is big enough? Calculate the test statistic and p-value. Write a meaningful conclusion.

Suppose the doctors at a local office take a health survey of 100 adult female patients with similar weight who have had appointments in the last week. According to their medical file, the 100 participants all weigh between 140 – 149 lbs. One of the survey questions asks participants to list their current weight. The accompanying tables show the relative frequency of weights measured by the physician for the 100 participants and the relative frequency of weights recorded in the survey for the 100 participants. Note that some of the weights reported in the survey did not fall between 140 – 149 lbs. Weights reported by physician (to the nearest pound) Weights recorded by participants Weight (in pounds) Relative frequency Weight (in pounds) Relative frequency 140 0.12 140 0.32 141 0.09 141 0.04 142 0.17 142 0.05 143 0.06 143 0.04 144 0.14 144 0.07 145 0.11 145 0.23 146 0.04 146 0.01 147 0.10 147 0.01 148 0.09 148 0.03 149 0.08 149 0.02 Total 1.00 Total 0.82 Select the statements that are…
