Hey, I am able to help you today :)

Step 1 - Simplify:
420x^2 - 18 = 2082

Step 2 - Add 18 to both sides:
420x^2 = 2082 + 18

Step 3 - Simplify 2082 + 18 to 2100:
420x^2 = 2100

Step 4 - Divide both sides by 420:
x^2 = 2100/420

Step 5 - Simplify 2100/420 to 5
x^2 = 5

Step 6 - Simplify:
x = 5

Step 7 - Check your answer:
10 x 42 x 5 - 18 =2082

Hope this helps you today :)

identify the type i error and the type ii error that corresponds to the given hypothesis. the proportion of people who write wit
djverab [1.8K]

Type I error is:

" Reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is actually 0.29 "

Type II error is:

"Fail to reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is actually different from 0.29 "

<u>What is proportion?</u>

An equation in which two ratios are made equal is called a proportion. For instance, you could write the ratio as 1: 3 (for every one boy, there are three girls), which means that 14 of the population is made up of boys and 34 of the population is made up of girls.

In Statistics, a  type I error is the rejection of a true null hypothesis

and  a type II error is the non-rejection of a false null hypothesis

Given that p = 0.29 is accepted

Now type I error is

C. Reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is actually 0.29

i.e. (false positive)

and type II error here is

B. Fail to reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is actually different from 0.29.
