1. can anyone explain to me what “give your answer to the nearest 0.05” is?

In a pic, (b), I calculated as 0.8+0.7 because at least one of them includes one and two. But the answer is 0.94. Can anyone help me with this?

Can anyone help me with (b)? I have no clue.

I multiply x value by relative frequency and then calculate the mean and median but different answer came out. Can anyone help me with this?

(a) can anyone help me with how to calculate the second quartile Q(2)?
(b) I dont understand the question. Can anyone help me with?

Round your answer to the nearest 0.05. For example, if you get 0.77, return 0.75. If you get 0.79, return 0.8. It’s like rounding to the nearest tenth, but by half.

Find P(C \cap D) and then use the inclusion-exclusion formula.

Show your steps; for mean your steps look fine. For median, find out for what X do we have the 50th percentile.

That’s the median.

Review boxplots (which is a PrepSwift video, if that helps).
