Answer:

$E = 3.46\ movies$

Step-by-step explanation:

The formula to find the error is:

$E = z_{\frac{\alpha}{2}}\frac{\sigma}{\sqrt{n}}$

Where:

$\sigma$ is the standard deviation

n is the sample size

n = 80 people

$\sigma$ = 12 movies

Then

$1- \alpha$ = confidence level = 0.99

$\alpha= 1-0.99$

$\alpha = 0.01\\\\\frac{\alpha}{2} = 0.005$

We look for the Z value: $Z_{0.005}$

$Z_{0.005}=2.58$ Looking in the normal standard tables

Therefore:

$E =2.58*\frac{12}{\sqrt{80}}\\\\E = 3.46\ movies$

Find a8 when a1= 9, d = 4 of the arithmetic sequence whose first term is a1 and common difference is d.

Gelneren [198K]

General Arithmetic Terms

$\displaystyle \large{a_n = a_1 + (n - 1)d}$

We want to find a8; we know:

a1 = 9
d = 4

Substitute in the formula.

$\displaystyle \large{a_n = 9 + (n - 1)4} \\ \displaystyle \large{a_n = 9 + 4n - 4} \\ \displaystyle \large{a_n = 4n + 5}$

To find a8, substitute n = 8

$\displaystyle \large{a_8= 4(8) + 5} \\ \displaystyle \large{a_8= 32 + 5} \\ \displaystyle \large{a_8= 37}$

Hence, the 8th term of sequence is 37
