A quantitative analysis teacher wants to see if there is any difference in the abilities of students enrolled in statistics in the summer and in the fall. Examination scores from a random sample of students enrolled this fall and from a random sample of students enrolled in the summer were selected. You are given the following information. x σ n Fall 74 17.06 35 Summer 84.77 19.01 28 Refer to Exhibit 10-30. What conclusion can be reached about the difference in the average final examination scores between the two classes? (Use a .05 level of significance.) There is a statistically significant difference in the average final examination scores between the two classes. There is no statistically significant difference in the average final examination scores between the two classes. It is impossible to make a decision on the basis of the information given. There is a difference, but it is not significant.

Question 4 What is the likelihood of the linear correlation between X and Y that you computed in a distribution where the linear relationship is zero if X = {2,1,2,1,4,3,3,3,3,3} and Y = {1,3,4,3,1,4,2,2,1,1}? Express your answer as a percentage, rounding it off to the nearest whole number.
Using the research scenario and data from Table2 below, conduct appropriate statistical analysis in Jamovi and answer questions 1-5. Research scenario: You hear a lot of talk about increasing global temperature, so you decide to see for yourself if there has been an actual change in recent years. You know that the average land temperature from 1951-1980 was 8.79 degrees Celsius. You find annual average temperature data from 1981-2017 (Table 1) and decide to look at whether there is a difference between the average temperature in the period between 1951-1980 and the average temperature in the period between 1981-2017. Table 2. Average land temperature from 1951-1980 in degrees Celsius. Year Temp Year Temp Year Temp Year Temp 1981 9.301 1991 9.336 2001 9.542 2011 9.65 1982 8.788 1992 8.974 2002 9.695 2012 9.635…
