Answer:
Since the sample size is larger than 30, the cognitive psychologist can assume that the sampling distribution of M will be approximately normal.
Step-by-step explanation:
We use the central limit theorem to solve this question.
The Central Limit Theorem estabilishes that, for a random variable X, with mean
and standard deviation
, a sample size larger than 30 can be approximated to a normal distribution with mean
and standard deviation 
So
Since the sample size is larger than 30, the cognitive psychologist can assume that the sampling distribution of M will be approximately normal.
Yes because without a y-intercept it goes through 0. and can you explain the next part?
Answer:
4.44
Step-by-step explanation:
8 times 10/8+10
80/18=4.44
Answer: D because the two longer sides are 7 unites longer, meaning you need to add 14 (7x2) to the final product
