Answer:
(3.442 ; 6.558)
Step-by-step explanation:
Given :
Mean score after patient is given the magnet treatment :
Mean score, xbar = 5
Standard deviation, s = 2.4
Sample size, n = 20
The confidence interval :
Mean ± margin of error
Margin of Error = Tcritical * standard error
The critical value at 95%, df = 20 - 1 = 19
Tcritical = 2.093 (T-student distribution)
The standard error = s/√n = 2.4 / √20 = 0.5367
The margin of error = 2.903 * 0.5367 = 1.558
The confidence interval :
Xbar ± Margin of error
5 ± 1.558
(3.442 ; 6.558)
Answer:
6
Step-by-step explanation:
2x2=4
3x2=6
:D
To find it you have to line them up for an example
2;2,4,6,8
4;4,8
And there you see a common number and its 4 and 8 if you wanted least then you would take the 4
To calculate for the percent of decrease:
First: work out the difference between the two numbers that you are given with.
Decrease = Original Number - New Number
Second: divide the decrease by the original number and multiply the answer by 100.
In formula terms it would look like this percent of decrease = Decrease ÷ Original
Number × 100
= (87-75) / 87 x 100
= 12/87 x 100
= 0.137931034 x 100
=13.79%
