For each problem students will write out all steps of hypothesis testing including populations, hypotheses, cutoff scores, and all relevant calculations.

A nationwide survey in 1995 revealed that U.S. grade-school children spend an average of µ = 8.4 hours per week doing homework. The distribution is normal with σ = 3.2. Last year, a sample of n = 100 grade-school children was given the same survey. For this sample, the mean number of homework hours was 7.1. Has there been a significant change in the homework habits of grade-school children? Test with α = .05.

Students will follow the hypothesis testing steps for each problem. They will compute the problem using the SPSS program. They will write the results in appropriate APA format and interpret the results. Steps of hypothesis testing will be typed out in a word document, as well as a copy and paste of the SPSS output. For the following problems, you will: Do all steps of hypothesis testing Populations and hypotheses Write out the steps you would do to calculate t...

In each problem show all steps of the hypothesis test. If some of the assumptions are not met, note that the results of the test may not be correct and then continue the process of the hypothesis test. 1. The Kyoto Protocol was signed in 1997, and required countries to start reducing their carbon emissions. The protocol became enforceable in February 2005. In 2004, the mean CO2 emission was 4.87 metric tons per capita. Table 7.3.3 contains a random sample...

all hypothesis testing problems must include the null and alternative hypotheses and report the p-value of the data. A random sample of 45 students took an SAT preparation course prior to taking the SAT. The sample mean of their quantitative SAT scores was 575 with a s.d. of 90, and the sample mean of their verbal SAT scores was 530 with a s.d. of 110. a) Construct 95% confidence intervals for the mean quantitative SAT and the mean verbal SAT...
