Suppose a bus arrives at a bus stop every 35 minutes

Ratling [72]

Answer:

3/7

Step-by-step explanation:

The probability of at least is 1 - the probability of at most

P(at least x) = 1 - P(at most x)

The given is:

1. A bus arrives at a bus stop every 35 minutes

2. You arrive at the bus stop at a random time

3. You will have to wait at least 20 minutes for the bus

∵ The bus arrives at a bus stop every 35 minutes

∵ You arrive at the bus stop at a random time

∵ You will wait at most for 20 minutes for the bus

∴ P(at most 20 minutes) =

∵ P(at least 20 minutes) = 1 - P(at most 20 minutes)

∴ P(at least 20 minutes) = 1 -

∴ P(at least 20 minutes) =

- Simplify the fraction by divide up and down by 5 and you will get your answer!

eduard

Answer:

1) Fail to reject the Null hypothesis

2) We do not have sufficient evidence to support the claim that the mean distance students traveled to school from their current residence was different for males and females.

Step-by-step explanation:

A university administrator wants to test if there is a difference between the distance men and women travel to class from their current residence. So, the hypothesis would be:

$H_{o}: \mu_{F}-\mu_{M}=0\\\\ H_{a}: \mu_{F}-\mu_{M}\neq 0$

The results of his tests are:

t-value = -1.05

p-value = 0.305

Degrees of freedom = df = 21

Based on this data we need to draw a conclusion about test. The significance level is not given, but the normally used levels of significance are 0.001, 0.005, 0.01 and 0.05

The rule of the thumb is:

If p-value is equal to or less than the significance level, then we reject the null hypothesis
If p-value is greater than the significance level, we fail to reject the null hypothesis.

No matter which significance level is used from the above mentioned significance levels, p-value will always be larger than it. Therefore, we fail to reject the null hypothesis.

Conclusion:

We do not have sufficient evidence to support the claim that the mean distance students traveled to school from their current residence was different for males and females.
