Margin of error: 0.04; confidence level: 95%; from a prior study, bold p with bold overparenthesis on top is estimated by the de

GrogVix [38]

Answer: 235

Step-by-step explanation:

The formula to calculate the sample size :-

$n=(\hat{p}(1-\hat{p}))(\dfrac{z_{\alpha/2}}{E})^2$

Given : Estimated proportion $\hat{p}=0.89$

Margin of error : $E=0.04$

Significance level : $\alpha=1-0.95=0.05$

Critical value : $z_{\alpha/2} =1.96$

Now, the required sample size will be :-

$n=(0.89(0.11))(\dfrac{(1.96)}{0.04})^2$

$\Rightarrow\ n= 235.057\approx235$

Hence, the required minimum sample size = 235

The 2014 draft picks for the NBA basketball teams have heights that are approximately normally distributed with mean 79.1 inches

ryzh [129]

It is given that the mean is 79.1 inches and standard deviation is 3.0 inches so it follows:

$\mu=79.1,\sigma=3$

So the value from 75 to 81 is given by:

$\begin{gathered} P(75\leq x\leq81)=P(x\leq81)-P(x\leq75) \\ =P(z\leq\frac{81-79.1}{3})-P(z\leq\frac{75-79.1}{3}) \\ =P(z\leq0.63)-P(z\leq-1.36) \end{gathered}$

Use the table or a software to get the probability values and substitute to get the probability value as:

The probability is 0.6509.

Licemer1 [7]

Answer:

56 dollars are earned for recycling 28 pounds of copper.

Step-by-step explanation:

Quantity of copper recycled = $p$ pounds

Amount earned in dollars for recycling $p$ pounds of copper = $2p$

Also,

Quantity of copper recycled = $28$ pounds

Therefore,

Amount earned in dollars for recycling $28$ pounds of copper = $2(28)=56$ dollars

So,

56 dollars are earned for recycling 28 pounds of copper.
