1.) 4^3= 64

2.) a^2 + b^2=c^2
5^2 + 12^2 = c^2
25 + 144 = c^2
169= c^2
c =  \sqrt{169}  = 13
3.) a^2 + b^2 = c^2
24^2 + b^2 = 26^2
576 + b^2 = 676
b^2 = 100
b =  \sqrt{100}  = 10

Elodia [21]

Using the Central Limit Theorem, it is found that the mean of the sampling distribution of sample proportions is 0.37.

The <em>Central Limit Theorem</em> establishes that, for a <u>proportion p in a sample of size n</u>, the sampling distribution of sample proportions has:

  • Mean \mu = p.
  • Standard error s = \sqrt{\frac{p(1 - p)}{n}}

For this problem, about 37% of high school seniors have vaped in the past year, hence p = 0.37.

  • Then, the mean of the sampling distribution of sample proportions is 0.37.

WILL MARK BRAINLIEST PLEASE HELP! How many three-digit numbers are multiples of neither 5 nor 7?
Temka [501]
 Best Answer

999/7 is just over 142

 

100/7 is just over 14

 

so there are (142 - 14) = 128 numbers that are multiples of 7, hence there are 999-99-128 = 772 numbers that are not multiples of 7.

The researcher is interested to know if policy A (new) is more effective than policy B (old). Frame the hypothesis and describe
vesna_86 [32]

<u>Answer:</u>

<u>Null hypothesis: Policy B remains more effective than policy A.</u>

<u>Alternate hypothesis: Policy A is more effective than policy B.</u>

<u>Step-by-step explanation:</u>

Remember, a hypothesis is a  usually tentative (temporary until tested) assumption about two variables– independent and the dependent variable.

We have two types of hypothesis errors:

1. A type I error occurs when the null hypothesis (H0) is wrongly rejected.

That is, rejecting the assumption that policy B remains more effective than policy A when it is <em>actually true.</em>

2. A type II error occurs when the null hypothesis H0, is not rejected when it is actually false. That is, accepting the assumption that policy B remains more effective than policy A when it is <em>actually false.</em>
