Several years​ ago, 39​% of parents who had children in grades​ K-12 were satisfied with the quality of education the students r
BaLLatris [955]
<h2>Answer with explanation:</h2>

Let p be the population proportion  of parents who had children in grades​ K-12 were satisfied with the quality of education the students receive.

Given : Several years​ ago, 39​% of parents who had children in grades​ K-12 were satisfied with the quality of education the students receive.

Set hypothesis to test :

H_0: p=0.39\\\\H_a :p\neq0.39

Sample size : n= 1055

Sample proportion : \hat{p}=\dfrac{466}{1055}=0.441706161137\approx0.44

Critical value for 95% confidence : z_{\alpha/2}=1.96

Confidence interval : \hat{p}\pm z_{\alpha/2}\sqrt{\dfrac{p(1-p)}{n}}

0.44\pm (1.96)\sqrt{\dfrac{0.39(1-0.39)}{1055}}\\\\0.44\pm0.0299536805135\\\\0.44\pm0.03\\\\=(0.44-0.03, 0.44+0.03)\\\\=(0.41,\ 0.47)

Since , Confidence interval does not contain 0.39.

It means we reject the null hypothesis.

We conclude that 95​% confidence interval represents evidence that​ parents' attitudes toward the quality of education have changed.

The function f(x) = 200(0.5)x/50 models the amount in pounds of a particular
victus00 [196]

<u>Answer:</u>

29 years

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

  • Given the function f(x)= 200(0.5)^{\frac{x}{50} }, where x stands for the number of years since the material was put into the vault, we can plug 140 into x to find the amount leftover.
  • Another way of doing this is to change the function to f(x)=200(0.5^{\frac{1}{50} })^{x} which are equivalent functions, and then plug 140 into x. This function is helpful if you also needed to find the rate.
  • I'll use the 1st function because the question doesn't ask for the rate

f(x)= 200(0.5)^\frac{140}{50}}

From here I'll just use a calculator & get 28.7, or 29 years.
