20 - 3 = 10x
17 = 10x
17/10 = x
Answer:
function notation
Step-by-step explanation:
y=3x-2 Is a function notation 4.3 functions
Using the z-distribution, it is found that the 95% confidence interval to estimate the mean SAT math score in this state for this year is (472, 488).
We have the <u>standard deviation for the population</u>, which is why the z-distribution is used to solve this question.
- The sample mean is .
- The population standard deviation is .
- The sample size is .
The interval is given by:
We have to find the critical value, which is z with a p-value of , in which is the confidence level.
In this problem, , thus, z with a p-value of , which means that it is z = 1.96.
Then:
The 95% confidence interval to estimate the mean SAT math score in this state for this year is (472, 488).
