Median is the middle number, but since there is 6 numbers.
Put them in order first
23,39,40,40,43,50
Well in middle is 40 for both sides
So to solve median for this you'd add the two middle numbers together since there is even set of numbers.
40+40 =80 then divide by 2
80÷2=40
Median = 40
*Follow This Example for any other even sets of numbers for Median*
Answer:
95% confidence level should be used for a confidence interval.
The given confidence interval contains the value of 85 sec, so there is not sufficient evidence to support the claim that the mean is greater than 85 sec.
Step-by-step explanation:
0.05 significance level
1 - 0.05 = 0.95
0.95*100% = 95%
This means that a 95% confidence level should be used for a confidence interval.
Confidence interval is found to be −1.8 sec<μ<213.5 sec, what should we conclude about the claim?
Contains the value of 85 sec, thus there is not sufficient evidence to support the claim that the mean is greater than 85 sec.
45 yd. Area Is BH. the area of the base is 9. Times the height, 5, is 45
Answer:
2.5 hours
Step-by-step explanation:
Basically you can see there is 2 hours. Then since there is half an hour left, it will be .5 hours.
So you now have 2.5 hours.
The problem has missing information. But, i'll try to answer it.
1.5% should be converted into a decimal number before it can be added to 0.50P.
1.5% / 100% = 0.015
0.015 + 0.5P = 0
0.5P = -0.015
0.5P / 0.5 = -0.015/0.5
P = -0.03
To check:
0.015 + 0.5(-0.03) = 0
0.015 - 0.015 = 0
0 = 0
Since no information about the number of people in the squad is given, let us assume that the squad is composed of 30 people, So, P = 30
0.015 + (0.5*30) = 0.015 + 15 = 15.015
