That is the answer , i looked it up for you my self :)
The answer is going to be 18 because they if you take away 30 from
48 it gives you 18...
The distance between would be 3 3/4.
First, you need to get out of the negatives.
-2 1/4+ 2 1/4= 0
2 1/4+ 1 1/2= 3 3/4
I’m sorry i this isn’t what your looking for :/
Part A:
From the central limit theorem, since the number of samples is large enough (up to 30), the mean of the the mean of the average number of moths in 30 traps is
0.6.
Part B:
The standard deviation is given by the population deviation divided by the square root of the sample size.

Part C:
The probability that an approximately normally distributed data with a mean, μ, and the standard deviation, σ, with a sample size of n is greater than a number, x, given by

Thus, given that the mean is 0.6 and the standard deviation is 0.4, the probability that <span>the average number of moths in 30 traps is greater than 0.7</span> given by:
Your answer will be 2.181818
