please provide correct answers and a good format table.I will also attach some pictures how the table should be.
Find the following for this data on the length of an eruption of a geyser at Yellowstone to the amount of time until the next eruption. Geyser Eruption Data Length of Eruption (in minutes) Time until next Eruption (in minutes) 3 4.54 2.53.55 2 68 89 83 62 75 9257 Step 1 Plot the data points. Be sure to: Title your graph Label each axis including units Use appropriate scales Step 2 Identify the correlation. Step 3 Sketch the linc of best fit. Step 4 Identify two points on the line. Step 6 Write an equation using slope and the y-intercept. Show all work. Step 7 Use your line and its equation to predict how long until the next eruption if the geyser only erupted for 1 minute. Show all work. Step 5 is: "find slope of line of best fit. Show all work."Please show all work!
question 9
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 dates 5 years 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 data is given in the table below. Complete parts (a) through (c) below. Observation 1 2 3 4 5 6 1/25 3/19 5/30 7/3 9/13 11/7 41.6 72.7 72.4 65.9 64.2 68.6 49.3 72.1 76.6 69.4 69.8 70.5 Date Initial Depth, X¡ Depth Five Years Later, Y; What is your conclusion regarding Ho? A. Do not reject Ho. There is not sufficient evidence at the α = 0.05 level of significance to conclude that the clarity of the lake is improving. B. Do not reject Ho. There is sufficient evidence at the x = 0.05 level of significance to conclude that the clarity of the lake is improving. C. Reject Ho. There is sufficient evidence at the x = 0.05 level of significance to conclude that the clarity of the…

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 dates 5 years 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 data is given in the table below. Complete parts (a) through (c) below Observation 3 4 Date 1/25 3/19 5/30 7/3 9/13 11/7 Initial Depth, X, 57.1 67.5 70.3 41.2 70.9 44.3 Depth Five Years Later, Y, 54.6 67.7 67.4 41.9 66.6 47.6 a) Why is it important to take the measurements on the same date? O A. Those are the same dates that all biologists use to take water clarity samples. O B. Using the same dates maximizes the difference in water clarity. O C. Using the same dates makes it easier to remember to take samples. O D. Using the same dates makes the second sample dependent on the first and reduces variability in water clarity attributable to date. b) Does the evidence…
