Please help me with this question. A researcher studies water clarity at the same location in a lake on the same dates during the course of a year and repeats the measurements on the same datesyears later. The researcher immerses a weighted disk painted black and white and measures the depth (in inches) at which it is no longer visible. The collected dagiven in the table below. Complete parts (a) through (c) below.Observation234Date1/25 3/19 5/30 7/39/13 11/7Initial Depth, X;61.6 38.3 49.567.2 48.144.2Depth Five Years Later, Y;69.1 38.2 54.1 69.8 54.7 46.1'C. Reject H,. There is sufficient evidence at the a= 0.05 level of significance to conclude that the clarity of the lake is improving.D. Do not reject Ho. There is not sufficient evidence at the a = 0.05 level of significance to conclude that the clarity of the lake is improving.c) Draw a boxplot of the differenced data. Does this visual evidence support the results obtained in part b)?Choose the correct graph below.А.OB.OC.OD.-8-8-8DifferenceDifferenceDifferenceDifference
