Aresearcher is examining the relationship between iq and crime. she calculates the mean for her sample as 96.24 on a standard iq score. she finds a standard deviation of 8.62 and has a sample of 200. using this information, answer the following questions.

1.1 what is the standard error for her sample?

The standard error for her sample is SE = 0.6095

Step-by-step explanation:

By definition, the standard error of the mean is:

Where:

is the standard deviation

is the sample size.

For the information provided in the problem we know that:

Then we introduce these values in the formula of the error to obtain the value.

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

your answer   is c
