The director of research and development is testing a new medicine. The director claims that the mean time in which the medicine relieves pain is less than 318 seconds. For a random sample of 20 patients, the mean time in which the medicine relieved pain was 308 seconds with a standard deviation of 24 seconds. Using a level of significance of 0.01, is there sufficient evidence to support the director’s claim? Assume the population distribution is approximately normal. Step 5 of 5: Draw a conclusion and interpret the decision.
Currently patrons at the library speak at an average of 62 decibels. Will this average increase after the installation of a new computer plug in station? After the plug in station was built, the librarian randomly recorded 40 people speaking at the library. Their average decibel level was 69.8 and their standard deviation was 18. What can be concluded at the the a = 0.05 level of significance? a. For this study, we should use Select an answer b.

Use z scores to compare the given values. The tallest living man at one time had a height of 238 cm. The shortest living man at that time had a height of 142.4 cm. Heights of men at that time had a mean of 175.45 cm and a standard deviation of 5.59 cm. Which of these two men had the height that was more extreme? ... Since the z score for the tallest man is z = 0 and the z score for the shortest man is z = the man had the height that was Im- more extreme. (Round to two decimal places.) shortest tallest

Use z scores to compare the given values. Based on sample data, newborn males have weights with a mean of 3282.7 g and a standard deviation of 689.7 g. Newborn females have weights with a mean of 3017.5 g and a standard deviation of 722.2 g. Who has the weight that is more extreme relative to the group from which they came: a male who weighs 1500 g or a female who weighs 1500 g? Since the z score for the male is z = more extreme. (Round to two decimal places.) and the z score for the female is z = [ =, the has the weight that is
The manufacturer claims that your new car gets 23 mpg on the highway. You suspect that the mpg is less for your car. The 50 trips on the highway that you took averaged 19.8 mpg and the standard deviation for these 50 trips was 7.4 mpg. What can be concluded at the � = 0.10 level of significance?
