Identify the type I error and the type II error that corresponds to the given hypothesis. The proportion of people who write wit
Umnica [9.8K]

Answer:

Type 1 error :

D. Reject the claim that the proportion of people who write with their left hand is 0.32 when the proportion is actually 0.32.

Type 11 error :

C. Fail to reject the claim that the proportion of people who write with their left hand is 0.32 when the proportion is actually different from 0.32.

Step-by-step explanation:

A type 1 error is committed when a true null rejected. That is an incorrect rejection of a true null. Hence, by rejecting the claim that proportion ofbpop

Type 2 error is made when a false null is adopted. Here, we fail to reject a false null. In the scenario above, type 11 error will be made if we fail to reject the claim that proportion of People who write with their left hand is 0.32, when the proportion is correctly not 0.32

Calculate CDEFtrapezium
pantera1 [17]

。☆✼★ ━━━━━━━━━━━━━━  ☾  

You need to find the length of A F and BC first

Lets call BC --> 'x'

Lets form an equation

9 + 9 + x + x = 28

18 + 2x = 28

- 18

2x = 10

/ 2

x = 5

So now we have the length BC

We can subtract this length from the 11cm to find the vertical height of the trapezium

11 - 5 = 6

Now we have all we need to work it out.

area = (a + b) / 2 x h

area = (5 + 9) / 2 x 6

area = 42 cm^2

Have A Nice Day ❤

Solve for x, where x is a real number.
Alex787 [66]

Hello!

First of all, let's undo the square roots by squaring both sides.

6x+2=9x-8

We subtract 9x from both sides.

-3x+2=-8

We subtract 2 from both sides.

-3x= -10

We divide both sides by -3.

x=10/3

I hope this helps!
