Scientists suspect that females can smell a particular chemical with an intensity greater than that of males. It is understood that there is a genetic component which affects the sensitivity to this chemical as well. 7 sets of full blood siblings are put near the chemical and asked to rate its intensity on a scale of 0 to 10. (0 means cannot smell.) Here are the results:Please state: 1. Qualitative (Categorical) or Quantitative (Numeric)• If Qualitative: Goodness of Fit or Test of Homogeneity/Independence?• If Quantitative: Proportions or Means?2. State the null and alternative hypotheses. 3. What distribution would you use to conclude the test, assuming all necessary assumptions weresatisfied? If Degrees of Freedom are involved, state them.

The calibration of a scale is to be checked by weighing a 11 kg test specimen 25 times. Suppose that the results of different weighings are independent of one another and that the weight on each trial is normally distributed with o = 0.200 kg. Let u denote the true average weight reading on the scale. (a) What hypotheses should be tested? Ho: H = 11 Ha: u + 11 Ho: H + 11 H3i H 11 a (b) With the sample mean itself as the test statistic, what is the P-value when x = 10.83? (Round your answer to four decimal places.) What would you conclude at significance level 0.01? Conclude that the true mean measured weight differs from 11 kg. Conclude that the true mean measured weight is the same as 11 kg. (c) For a test with a = 0.01, what is the probability that recalibration is judged unnecessary when in fact u = 11.2? (Round your answer to four decimal places.)

A health insurance company conducted an independent study and collected data from a random sample of 265 individuals for prescription allergy relief medicine. The sample mean is found to be 17.5 dollars/year, with a sample standard deviation of 5.6 dollars/year. They have also collected data for non-prescription allergy relief medicine. An independent random sample of 220 individuals yielded a sample mean of 18.5 dollars/year, and a sample standard deviation of 4.5 dollars/year. Since the sample size is quite large, it is assumed that the population standard deviation of the sales (per person) for prescription and non- prescription allergy…
