melisa1 [442]

Answer:

Step-by-step explanation:

Given that a survey was conducted that asked 1004 people how many books they had read in the past year.

Results are:

x bar =12.5

s = 16.6

n = 1004

Std error of sample = \frac{s}{\sqrt{n-1} } =\frac{16.6}{\sqrt{1003} }\\=0.524152\\=0.524

Since population std dev is not known t critical value can be used for confidence interval.

df = 1004-1 =1003

t critical = 1.96

Margin of error = 1.96(std error) =1.027

Confidence interval lower bound = 12.5-1.027 = 11.473

Upper bound = 12.5+1.027 = 13.527

Seven more than the product of a number and <br> 8<br> is equal to <br> 5
yuradex [85]
8x + 7 = 5

A "product" is the result of a multiplication operation.  So the product of a number, ( which we will call x,) and 8 would be 8x. (Or 8*"x" number) 7 more than that product would be 8x + 7 = 5

Hope that this helps!
