A researcher is conducting a stress intervention on high school students and wants to determine if students have improved. The average stress score at baseline is 72with a variance of 14. The average follow up was 82 with variance =16. The teacher calculated the difference between the follow up and baseline for each student and found that 95% conf intervals for mean paired difference was (-0.956, 15.957) n=10 Using the conf interval...calculate average and standard deviation of the paired differences.

Hydrocarbon emissions from cars are known to have decreased dramatically during the 1980s. A study was conducted to compare the hydrocarbon emissions at idling speed, in parts per million (ppm), for automobiles from 1980 and 1990. Twenty cars of each model year were randomly selected, and their hydrocarbon emission levels were recorded. The standard deviations are 281.07 ppm and 119.39 ppm for 1980 and 1990 models respectively. Test if the variances of the two models are equal.
The main number of English courses taken in a two-year time period by male and female college students is believed to be about the same. An experiment is conducted and data are collected from 29 males and 16 females. This males took an average of three English courses with a standard deviation of 0.8. The females took an average of four English courses with a standard deviation of 1.0. Are the means statistically the same? Assume that the variances are not equal. Test at 5% level of significance.

A professor gave a final examination to his 400 4th year BS Criminology students. He noted that 40 of the female students had a mean performance of 122 and a variance of 60 while 35 of the male students had a mean performance of 126 and a variance of 74. Assuming that the students were randomly selected and the distribution is normal, is there a reason to believe that there is significant difference between the examination mean performance of the male and female students. Use 0.01 level to test its significance.
The national average for the number of students per teacher for all U.S. public schools in 15.9 Arandom sample of 12 school districts from a moderately populated area showed that the mean number of students per teacher was 19.2 with a variance of 4.41. Estimate the true mean number of students per teacher with 95% confidence. How does your estimate compare with the national average?

The average depth of the Hudson Bay is 305 feet. Climatologists were interested in seeing if theeffects of warming and ice melt were affecting the water level.

Can it beconcluded at the 0.05 level of significance that the average depth has increased?
An article about “Relative Controllability of Dissimilar Cars” reported a study in which 14 subjects were asked to parallel-park two cars having very different wheel bases and turning diameter. The time (in seconds) for each subject was recorded and found that the sample mean and sample variance of the difference were 1.21 seconds and 160.7824, respectively. The researcher claims that the population mean difference of time taken is (4.79,7.21) seconds. With what level of confidence can this statement be made?
