Answer:
Step-by-step explanation:
We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean
For the null hypothesis,
µ = 152.5
For the alternative hypothesis,
µ ≠ 152.5
This is a two tailed test.
Since no population standard deviation is given, the distribution is a student's t.
Since n = 231
Degrees of freedom, df = n - 1 = 231 - 1 = 230
t = (x - µ)/(s/√n)
Where
x = sample mean = 148.9
µ = population mean = 152.5
s = samples standard deviation = 27.4
t = (148.9 - 152.5)/(27.4/√231) = - 2
We would determine the p value using the t test calculator. It becomes
p = 0.047
Since alpha, 0.05 > thanthere sufficient evidence to conclude that the self-efficacy of adults who have experienced childhood trauma differs from that in the general population of individuals the p value, 0.047, then we would reject the null hypothesis. Therefore, At a 5% level of significance, there is sufficient evidence to conclude that the self-efficacy of adults who have experienced childhood trauma differs from that in the general population of individuals
Answer:
240/r = h
Step-by-step explanation:
480π = πr2h Write out the equation
480 = r2h Cancel out π on both sides
240 = rh Divide by 2 on both sides
240/r = h Divide by r to isolate h and get your answer
Answer:
Number of wallpaper needed = At/Aw = 355.3/75
N = 4.74 ~= 5 rolls
Step-by-step explanation:
Given;
Length of the room = 12 feet 6 inches = 12.5 ft
Breadth of the room = 10 feet 6 inches= 10.5ft
Height of the room = 8 feet
Window = 4 ft by 3ft
door = 7ft by 3 ft
Wall paper = 30 inches by 30ft = 2.5ft by 30ft
The total area of the walls of the room is;
Area = Area of the four walls - Area of the two windows and a door.
A = 2LH + 2BH - Area of windows and door
A = 2(12.5×8) + 2(10.5×8) - 2(4×3) -(7×3)
A = 323ft^2
Allowing 10% waste, total area of wallpaper needed is;
At = 323 × 1.10 = 355.3ft^2
Area of wallpaper Aw= 2.5×30 = 75ft^2
Number of wallpaper needed = At/Aw = 355.3/75
N = 4.74 ~= 5 rolls
