65 female soccer players and 65 male soccer players were randomly selected from the state of New York. Their body temperatures were taken and were recorded. The mean of the male body temperatures was 98.105 degrees Farenheit and their standard deviation was .699. The mean of the female body temperatures was 98.394 degrees Farenheit and their standard deviation was .743. Is their a significant difference between the means of the two populations? Let alpha be .05. What are the hypotheses equal to? What is the test statistic and p value?

At a local store, 65 female employees were randomly selected and it was found that their mean monthly income was $625 with a standard deviation of $121.50. 75 male employees were also randomly selected and their mean monthly income was found to be $667 with a standard deviation of $168.70. Find the test statistic to test the hypothesis that male employees have a higher monthly income than female employees. Use a =0.01. The test statistic is: 1.652 - 1.705 -1.533...

A researcher at a medical college conducted a study of 60 randomly selected male soccer players and concluded that frequently "heading" the ball in soccer lowers players' IQs. The soccer players were divided into two groups, based on whether they averaged 10 or more headers per game. Mean IQs were reported in the article, but the sample sizes and standard deviations were not given. Suppose that these values were as given in the accompanying table. n Sample Mean Sample sd...

In a survey of 100 randomly selected professional soccer players, the mean counter movement jump height was x=55.08cm. Suppose that somehow we knew that the population standard deviation of the counter movement jump is 5.52 cm. Find a 90% confidence interval estimate of the mean CMJ of all professional soccer players.

22 seventh-graders were randomly selected from a middle school and their IQ was tested. One year later after they finished eighth-grade their IQ was tested again. They determined that the mean of the differences of these students was -.0121 and their standard deviation was .5. Let alpha be equal to .05. Is there enogh evidence to say that the differences between the IQs of the two academic years was less than -.01? What are the hypotheses equal to? What is...

At a college, 61 female students were randomly selected and it was found that their monthly income had a standard deviation of $230.85. For 121 male students, the standard deviation was $320.53. Test the claim that variance of monthly incomes is higher for male students than it is foi female students. Use a = 0.01.

One male and one female dam rat pup were randomly selected from 8 litters to perform the swim maze. Each pup was placed in the water at one end of the maze and allowed to swim until it escaped at the opposite end. If the pup failed to escape after a certain period of time, it was placed at the beginning of the maze and given another chance. The experiment was repeated until each pup accomplished three successful escapes. The...
