Answer:
a. N(500, 100)
Step-by-step explanation:
The normal probability distribution, with mean M and standard deviation S, can be represented in the following notation.
N(M,S).
In this problem, we have that:
Mean = 500
Standard deviation = 100
Which of the following options would be the correct way to represent the information?
a. N(500, 100)
Answer:
The null hypothesis is that all the different teaching methods have the same average test scores.
H0: μ1 = μ2 = μ3 = μ4 = μ5
The alternative hypothesis is that at least one of the teaching methods have a different mean.
Ha: at least one mean is different. (μ1 ≠ μi)
Step-by-step explanation:
The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean. While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.
For the case above, let μ represent the average test scores for the teaching methods:
The null hypothesis is that all the different teaching methods have the same average test scores.
H0: μ1 = μ2 = μ3 = μ4 = μ5
The alternative hypothesis is that at least one of the teaching methods have a different mean.
Ha: at least one mean is different. (μ1 ≠ μi)
Answer:
5.93 * 10^7
7 represents the amount of times you moved the decimal
I believe 64x-8 is the correct answer.
