One measure of general health is your body mass index (BMI). Adults with a BMI between 18.5 and 24.9 are generally considered to

soldi70 [24.7K]

Answer: 0.1797

Step-by-step explanation:

Given : $\mu=24.5\ \ ; \sigma=1.2$

Let x be the random variable that represents BMI for adults in this country.

We assume that BMI for adults in this country is normally distributed.

Then, z-score for x=25.6 , $\because z=\dfrac{x-\mu}{\sigma}$

$\Rightarrow\ z=\dfrac{25.6-24.5}{1.2}\approx0.9167$

Using z-value table , we have

The probability that the person's BMI is more than 25.6 :

$P(x>25.6)=P(z>0.9167)=1-P(z\leq0.9167)\\\\=1- 0.8203413=0.1796587\approx0.1797$

Hence, the probability that the person's BMI is more than 25.6 = 0.1797

Hence, the probability that the person's BMI is more than 25.6 = 0.1796

Hence, the probability of the stick's weight being 2.23 oz or greater = 0.0174

mamaluj [8]

Answer:

356

Step-by-step explanation:

We are given that p=0.7, and a 90% confidence interval. Also, we know the margin of error to be 0.04, the sample size is calculated as:

#The sample size is calculated as:

$ME=z_{\alpha/2}\sqrt\frac{p(1-p)}{n}}\\\\0.04=1.645\sqrt\frac{0.7(1-0.7)}{n}\\\\n=\frac{0.7\times 0.3}{(0.04/1.645)^2}\\\\n=355.17\approx 356$

Hence, at least 356 apples must be sampled to get a true proportion with the 4% ME.
