An engineering firm wants to test out a new anti-reflective coating for lenses in a camera. They first measured the percent of reflection on a collection of the lens and then applied the coating. They then measured the reflection again. They continued this process for ten lenses. (dif = before – after)The 95% confidence interval was (1.3, 4.5). Finish the following sentence”We are 95% confident that the [word1] reflection before the coating was between 1.3 [word2] to 4.5 [word3] then after the coating.”

A travel firm is interested in determining if there is a difference in how customers will receive a new term of service contract based on their age (young, middle aged or senior). A small sample of individuals were asked if they strongly agreed, agreed, disagreed or strongly disagreed with a new term of service contract.  Which cell has the highest contribution to the Chi Square Test Statistic? Age Agreement young strongly agree young agree young agree young disagree young disagree young strongly disagree middle agree middle agree middle disagree middle strongly disagree middle agree middle agree middle agree middle strongly agree middle strongly agree senior agree senior agree senior disagree senior disagree senior disagree
