Use z scores to compare the given values. Bannd on sample data, newbom males have weights with a mean of 3293.8 g and a standard deviation of 567.1 g. Newbom females have weights with a mean of 3075.9g and a standard deviation of 602.3 g. Who has the weight that is more extreme relative to the group from which they came: a male who weighs 1700 g or a female who weighs 1700 g? Since the z score for the male is z=and the z score for the female is z=, the V has the weight that is more extreme. (Round to two decimal places.)

Scores on a statistics final in a large class were normally distributed with a mean of 73 and a standard deviation of 6. Use the empirical rule to answer the following questions. a. Estimate the proportion of the scores less than 67. b. Estimate the proportion of the scores more than 85. c. Estimate the proportion of the scores between 61 and 79.
When you purchased your car, the dealer told you that your average gas mileage on your car was 30mpg, but you suspect that is might be lower than that. You conduct a sample over 30 days, and find that your sample average is only 28 mpg, with a standard deviation of 8.2 mpg. You conduct a hypothesis test, and find a P-value of 9.6%. What are your conclusions? Use an a level of 5% O Reject H, and accept H4. You have strong evidence that your car does get less than 28 mpg, on average. O Accept H.. You have strong evidence that your car gets 28 mpg, on average. O Reject H4. You have strong evidence that your car gets more than 28 mpg, on average. O Fail to reject Ho. You do not have strong evidence that your car gets less than 28 mpg, on average.
Currently patrons at the library speak at an average of 65 decibels. Will this average decline 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 61.8 and their standard deviation was 20. What can be concluded at the the a 0.01 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: Select an answer v Select an answer V C. The test statistic ? (please show your answer to 3 decimal places.) d. The p-value (Please show your answer to 4 decimal places.) e. The p-value is ? va f. Based on this, we should Select an answer v the null hypothesis. g. Thus, the final conclusion is that ...
