Lina20 [59]

Answer: 97.72%

Step-by-step explanation:

Given : A shoe manufacturer collected data regarding men's shoe sizes and found that the distribution of sizes exactly fits the normal curve.

Let x be the random variable that represents the shoe sizees.

Also, The population mean = $\mu=11$ ; Standard deviation: $\sigma=1.5$

Formula for z:-

$z=\dfrac{x-\mu}{\sigma}$

Put x= 8, we get

$z=\dfrac{8-11}{1.5}=-2$

Now, the probability that the male shoe sizes are greater than 8 :-

$P(x>8)=P(z>-2)=1-P(z\leq-2)\\\\=1-0.0227501=0.9772499\approx0.9772$

Hence, the percent of male shoe sizes are greater than 8 is 97.72%.

In a sample of 800 U.S. adults, 219 think that most celebrities are good role models. Two U.S. adults are selected from this sa

shutvik [7]

Answer:

Step-by-step explanation:

P=(219/800)×(218/799)≈0.0747≈0.075

800-219=581

P=(581/800)×(580/799)≈0.527

P( 1 think role models and one thinks not role models)+P(both thinks they are role models)=(219/800)×(581/799)+(219/800)×(218/799)=(219×581+219×218)/(800×799)

=[219(581+218)]/(800×799)

=(219×799)/(800×799)

=219/800

=0.27375

=0.274
