A random sample of 28 statistics tutorials was selected from the past 5 years and the percentage of students absent from each one recorded. The results are given below. Assume the percentages of students' absences are approximately normally distributed. Use Excel to estimate the mean percentage of absences per tutorial over the past 5 years with 90% confidence. Round your answers to two decimal places and use increasing order. Number of Absences 13.9 16.4 12.3 13.2 8.4 4.4 10.3 8.8 4.8 10.9 15.9 9.7 4.5 11.5 5.7 10.8 9.7 8.2 10.3 12.2 10.6 16.2 15.2 1.7 11.7 11.9 10.0 12.4

Problem 3-11 (Algorithmic) A recent survey by the New Statesman on British social attitudes asked respondents if they believe that inequality is too large. The survey found that 70% of the respondents do believe inequality is too large. In a sample of six British citizens, what is the probability that two believe inequality is too large? If required, round your answer to four decimal places.

A consumer research organization states that the mean caffeine content per 12-ounce bottle of a population of caffeinated soft drinks is 37.8 milligrams. You find a random sample of 48 12-ounce bottles of caffeinated soft drinks that has a mean caffeine content of 41.5 milligrams. Assume the population standard deviation is 12.5 milligrams. At α=0.05, what type of test is this and can you reject the organization’s claim using the test statistic?

If ΔONP is dilated from point N by a scale factor of segment NL over segment NP, which additional transformation could determine if ΔONP and ΔMNL are similar by the AA similarity postulate?Segments OM and LP intersect at point N; triangles are formed by points LNM and ONP; line k intersects with both triangles at point N. Rotate O'N'P' 180° about point N. Rotate O'N'P' 90° clockwise about point N. Translate point P' to point M. Translate point O' to point L.

100 POINTS!!! I need help asap 1) Which point is in the solution set for y < x+2? Explain your answer.Question 1 options:A. (0, 2) because when you graph y < x+2, it is a point on the boundary line.B. (2, 1) because when you graph y < x+2, it is a point that lies below the boundary line.C. (-2, 0) because when you graph y < x+2, it is the x-intercept of the boundary line.D. (1, 4) because when you graph y < x+2, it is a point that lies above the boundary line.2) A system of inequalities is shown:y ≤ x + 6y ≥ 9x − 9Which point is in the solution set of the system of inequalities shown? Explain your answer.Question 2 options:A. (-1, 7) because it lies below the boundary line y=x+6.B. (3, 2) because it lies above the boundary line y=9x−9.C. (-2, 2) because it lies above the boundary line y=9x−9 and below the boundary line y=x+6.D. (3, 10) because it lies below the boundary line y=9x−9 and above the boundary line y=x+6.3. (x, y) is the point of intersection of the boundary lines of the system of inequalities:y ≥ −3x + 5y ≤ x + 1Select the graph that represents a system of inequalities that includes the same point of intersection (x, y) in its solution set.Question 3 options:there are 4 pictures of different graphs but I cannot figure out how to upload pictures to brainly
