According to the scenario, computation of the given data are s follows,

Total rope = 46 feet

Number of person = 2

So, we can calculate the amount of rope each person get by using following formula,

Each person quantity = Total rope ÷ Number of person

By putting the value in the formula, we get

Each person quantity = 46 feet ÷ 2

= 23 feet

Hence, each person gets 23 feet of rope.

A study found that the average stopping distance of a school bus traveling 50 mph was 264 feet. a group of automotive engineers
lutik1710 [3]

Answer:

Step-by-step explanation:

Given that a  study found that the average stopping distance of a school bus traveling 50 mph was 264 feet.

Sample taken showed the following results

n=40\\\bar x =262.3 feet\\Std dev = \sigma= 3 ft

Since population std deviation is known and sample size is large, z test can be used.

H_0: \bar x=264\\H_a: \bar x

(Left tailed test)

Mean difference = 264-262.3 = 1.7

Std error = \frac{\sigma}{\sqrt{n} } \\=\frac{3}{\sqrt{40} } \\=0.474

Z = test statistic = mean diff/std error

= \frac{1.7}{0.474} \\=3.584

p value = 0.00017

Since p < alpha our 0.05 we reject null hypothesis

There is evidence to show that mean is less than 264 feet

(Assumptions:

Sample are randomly drawn

Sample represents the population
