A survey taken of 140 sports fans asked the question: "What is the most you have ever spent for a ticket to a sporting event?" T

Zarrin [17]

The IQR is 150 - 130 = 20. Using the 1.5(IQR) criterion we get 130 -1.5(20) = 100. Since the smallest observation of 85 is smaller than 100, it should be considered an outlier

A normally distributed population has a mean of 250 pounds

Dima020 [189]

Answer: 0.9746

Step-by-step explanation:

Given : A normally distributed population has a mean of 250 pounds and a standard deviation of 10 pounds.

i.e. $\mu=250$ $\sigma=10$

Sample size : n= 20

Let $\overline{x}$ sample mean values.

Then, the probability that this sample will have a mean value between 245 and 255 be

$P(245$

Hence , the probability that this sample will have a mean value between 245 and 255 is 0.9746 .

Robert traveled 80 miles per hour. What equation shows the relationship between distance traveled (d), speed (s), and time taken

Evgen [1.6K]

Answer:

$80 = \frac{d}{t}$
d=80t
$t = \frac{d}{80}$

Step-by-step explanation:

The relationship between distance traveled (d), speed (s), and time taken (t) can be represented the following expressions:

$s = \frac{d}{t}$
d = st
$t = \frac{d}{s}$

Using any of these expressions you can show the relationship. Substitute s = 80 for the speed.

$80 = \frac{d}{t}$
d=80t
$t = \frac{d}{80}$
