What is the number of samples (N) used in the study?b. State the value for F-countc. Using the significance level or the Alpha (α) value 4%, test the hypotheses in the study and provide the conclusion.d. How do you think the conclusions of the research are?
Kenneth, a competitor in cup stacking, claims that his average stacking time is 8.2 seconds. During a practice session, Kenneth has a sample stacking time mean of 7.8 seconds based on 11 trials. At the 4% significance level, does the data provide sufficient evidence to conclude that Kenneth's mean stacking time is less than 8.2 seconds? Accept or reject the hypothesis given the sample data below. H0:μ=8.2 seconds; Ha:μ<8.2 seconds α=0.04 (significance level) z0=−1.75 p=0.0401 Select the correct answer below: a. Do not reject the null hypothesis because the p-value 0.0401 is greater than the significance level α=0.04. b. Reject the null hypothesis because the p-value 0.0401 is greater than the significance level α=0.04. c. Reject the null hypothesis because the value of z is negative. d. Reject the null hypothesis because |−1.75|>0.04. e. Do not reject the null hypothesis because |−1.75|>0.04.

The p-value is Select an answer less than (or equal to) greater than αα Based on this, we should reject the null fail to reject the null accept the null Thus, the final conclusion is... There is sufficient evidence to conclude that sneaker brand and religious affiliation are dependent. There is insufficient evidence to conclude that the distribution of sneaker brand is not the same for each religion. There is insufficient evidence to…
A school psychologist was asked to assess a group of 17 students who failed their math exam. She screened for possible learning disabilities and wanted to check their global IQ scores. Each student was asked to complete a global IQ test. After conducting a correlation, she found that there was a strong positive correlation with r= 0.79 between IQ and math exam scores which was found to significant at p < 0.05. Based on the correlation, IQ was found to explain 61% of the variability in the student's math exam scores. After conducting the correlation, the teacher took another random group of 18 students who scored well in their math exam. She created two groups based on math exam scores (Group 1 high exam scores Vs Group 2 failed exam scores). The psychologist hypothesises that the students in the failed exam score group will have lower global IQs than students in the high exam score group who were used as a control group. A trial was conducted to assess the impact of IQ on math scores.…
