Step-by-step explanation:
Mixed number contain while and fraction number so,,,
0.1==>1/10 no whole
Answer:
5
Step-by-step explanation:
( 2 + 4 + 6 + 8) / 4 = 5
Answer:
a. We fail reject to the null hypothesis because zo = -5.84 < 1.65 = zα and P-value = 1 (approximately)
b. The confidence Interval for u1 - u2 is; 6.79 ≤ u1 - u2
c. The power of the test = 1 -
β = 0.998736
d. The sample size is adequate because the power of the test is approximately 1
Step-by-step explanation:
Given
Standard Deviations; σ1 = σ2 = 1.0 psi
Size: n1 = 10; n2 = 12
X = 162.5; Y = 155.0
Let X1, X2....Xn be a random sample from Population 1
Let Y1, Y2....Yn be a random sample from Population 2
We assume that both population are normal and the two are independent.
Therefore, the test statistic
Z = (X - Y - (u1 - u2))/√(σ1²/n1 + σ2²/n2)

0T= area of the square-(15*4)
=we will get the area of circle
area of circle=pi*r(square)
here r square is not there
and area is there
so the equation will be like this
r(square)=7*the area of circle \ 22
so the answer you can find
