since the n which is the sample size is 10, then the distribution is mound shaped.
why?
this is due to the fact that the random variable from which we took the sample is mound shaped.
The sampling distribution of the mean is normally distributed although the question says the random variable is not normally distributed. so the shape is bell shaped and normally distributed.
Yes they are similar. the rectangle on the left is 4 by 6. the rectangle on the right is 2 by 3. 4/6=2/3 2/3 is the simplified version of 4/6 this makes them similar
