Pachacha [2.7K]

Answer:

a) In the explanation.

b) P=0.09714

c) P=0.0866

d) p=0.208

Step-by-step explanation:

a) The sampling distribution will have this properties:

1 - The sampling distribution of a proportion is equal to the binomial distribution.

2 - The mean of the sampling distribution will be equal to the proportion of the population (0.328).

$\mu=\pi=0.328$

3 - The standard deviation will be equal to the square root of the product of the proportion and its complementary, divided by the sample size.

$\sigma_s=\sqrt{\pi(1-\pi)/n}=\sqrt{0.328*(1-0.328)/25}=0.094$

B) The fraction with sample proportion of 0.45 or higher is

$z=(p-\pi)/\sigma=(0.45-0.328)/0.094=1.298\\\\P(p\geq0.45)=P(z\geq 1.298)=0.09714$

C) The fraction with sample proportion of 0.20 or lower is

$z=(p-\pi)/\sigma=(0.2-0.328)/0.094=-1.362\\\\P(p\leq0.2)=P(z\geq -1.362)=0.0866$

D) The value of p that cuts off the lower 10% of the distribution corresponds to z=-1.28.

Then we have

$z=(p-\pi)/\sigma\\\\p=\pi+z\sigma=0.328+(-1.28)*0.094=0.328-0.120=0.208$

lauren rode her bike from her house to a friend house 3 1/3 miles away. on the first leg of her trip she rode uphill at 3 miles

spayn [35]

The uphill part of the ride would have taken 16 minutes and 40 seconds.

This can be found first by determining how many miles Lauren went during the downhill portion. This can be found by multiplying the speed by the time.

5mph * .5hrs = 2 1/2 miles.

Now we can determine how far she needs to go during the uphill portion by subtracting the downhill portion from the entire ride.

3 1/3 miles - 2 1/2 miles = 5/6 miles.

Now that we know she needs to go 5/6 miles for the uphill portion, we can divide the distance by the speed.

5/6 miles / 3 mile per hour = 5/18 hours = 16.67 mins or 16 mins and 40 seconds.
