Actually in this case we will make use of the z test statistic. In which we calculate for the z score and then use the standard normal distribution tables to find for the P value at the calculate z score.

 

z = (x – u) / s

z = (97 – 98) / 2

z = -0.5

 

The z value should be greater than 1.65 to for the null hypothesis to be accepted. Hence rejected.

Answer: the y intercept is -5

You can use the slope intercept form to find the answer. Aka y = mx + b

In this equation m is equal to the slope and b is equal to the y-intercept.

We already know the slope, 4. And we have two different point we can choose from. I’ll show how to solve with the first (1,-1) point.

How can the series {-6,-3+0+3+6+9+12+15} be denoted using Sigma Notation
Pachacha [2.7K]

Answer:

∑ₙ₌₁⁸ (3n − 9)

Step-by-step explanation:

This is an arithmetic series where the first term is -6 and the common difference is 3.  The nth term can be written as:

aₙ = a₁ + d (n − 1)

aₙ = -6 + 3 (n − 1)

There are 8 terms in this series, so the sum is:

∑ₙ₌₁⁸ [-6 + 3 (n − 1)]

Simplified:

∑ₙ₌₁⁸ (3n − 9)
