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.
Answer:
Step-by-step explanation:
We are given the Inequality:
First, we can simplify the expression. On the left side of Inequality, we can cancel 2; on the right side, we can cancel 2 out as well.
Simply, division!
2 divides 2 is 1; 2 divides 10 is 5.
Generally, it is not recommended to write 1 beside the variable nor write 1 as a denominator.
Simplify the expression:-
Therefore, the value of y is less than 5.
