This Week Last Week Step 1 Find the mean. mc015-3.jpg Find the mean. mc015-4.jpg Step 2 Find the mean absolute deviation. mc015-5.jpg Find the mean absolute deviation. mc015-6.jpg Step 3 Find the ratio of the differences of the means compared to the mean absolute deviation. mc015-7.jpg Find the ratio of the differences of the means compared to the mean absolute deviation. mc015-8.jpg Step 4 The difference in the means is about mc015-9.jpg times the mean absolute deviations. In which step did Daniela make the first error

Answer 1

Daniela made her error on step 3 because it says: 
"Find the ratio of the differences of the means compared to the mean absolute deviation.

She didn't find the difference between the today and last week means. She just put the mean as a whole.

Answer 2

 Daniela recorded the low temperatures during the school day last week and this week. Her results are shown in the table below.

This Week Last Week Step 1 Find the mean. mc015-3.jpg Find the mean. mc015-4.jpg Step 2 Find the mean absolute deviation. mc015-5.jpg Find the mean absolute deviation. mc015-6.jpg Step 3 Find the ratio of the differences of the means compared to the mean absolute deviation. mc015-7.jpg Find the ratio of the differences of the means compared to the mean absolute deviation. mc015-8.jpg Step 4 The difference in the means is about mc015-9.jpg times the mean absolute deviations. In which step did Daniela make the first error? well lets get to it so step 3 was  an error because 58 cant go into 15 so your final answer is step 3 have an amazing day all of you
