What is the median of 7, 12, 13, 40, 88, 95, 95 HURRY!!

1 answer:

4 0

To find the median you have to put all the numbers in order from smallest to largest and find the one that's in the middle.
All of the numbers listed are already in order, and the one that lies in the middle is 40. So the answer is 40.

Step-by-step explanation:

Given the data:

X : 18.0, 30.7, 19.8, 27.1, 22.3, 18.8, 31.8, 23.4, 21.2, 27.9, 31.9, 27.1, 25.0, 24.7, 26.9, 21.8, 29.2, 34.8, 26.7,31.6

True standard deviation (σ) = 4

α = 0.01

Mean (m) of the data:

Σ(X) /n = 520.7/20

m = 26.035 = 26.04

Uaing calculator :

Sample standard deviation (s) = 4.785

Null hypothesis : μ = 25

Alternative hypothesis : μ > 25

Test statistic (t) : (m - μ) / (s/√n)

t = (26.04 - 25) / (4.785/√20)

t = 0.972

We can obtain the p value using the pvalue from t score calculator :

df = n - 1 = 20 - 1 = 19

Decision:

If p < 0.01 ; reject null

p(0.972, 19) = 0.1716

Since p > 0.1716 ; we fail to reject the Null

Graph should represent "miles per gallon" that means the y axis are miles driven with x axis gallons used.

See image attached.

The fuel usage is approximately linear so the graph is a line. The origin of the graph (0,0) corresponds to the starting point in MIami, FL, where 0 gallon have been spent and 0 miles driven. the endpoint corresponds to Atlanta, GA, where 90 gallons have been spent and 660 miles driven. The domain is real numbers in the interval [0,90]. The x intercept is 0, the y intercept is also 0. The range is real numbers in the interval [0,660].
