Below, n is the sample size, p is the population proportion and p is the sample proportion. Use the Central Limit Theorem and the TI-84 calculator to find the probability. Round the answer to at least four decimal places.

n=111
p=0.54

Find the probability of P(05

Step-by-step explanation:

Hello!

The Central Limit Theorem allows you to approximate the sampling distribution of a variable to normal. In this case, if n≥30, you can approximate the distribution of the sample proportion to normal:

^p≈N(n*p; [p(1-p)]/n)

You need to calculate the percentage of the distribution that is between the two values of the sample proportion of 0.50 and 0.60, symbolically:

P(0.50≤^p≤0.60)

P(^p≤0.60)-P(^p≤0.50)

To reach the value of accumulated probabilities until 0.6 and 0.5 you have to standardize both values by subtracting the mean of the distribution (np) and dividing it by the standard deviation (√ [p(1-p)]/n)

Z=

^p= 0.6⇒

^p= 0.5 ⇒

Then:

P(Z≤1.27) - P(Z≤-0.85)= 0.89796 - 0.19766= 0.7003

I hope this helps!

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
