Kindly check explanation
Step-by-step explanation:
Given :
Sample size, n = 30
Tcritical value = 2.045
Null hypothesis :
H0: μ = 9.08
Alternative hypothesis :
H1: μ≠ 9.08
Sample mean, m = 8.25
Samole standard deviation, s = 1.67
Test statistic : (m - μ) ÷ s/sqrt(n)
Test statistic : (8.25 - 9.08) ÷ 1.67/sqrt(30)
Test statistic : - 0.83 ÷ 0.3048988
Test statistic : - 2.722
Tstatistic = - 2.722
Decision region :
Reject Null ; if
Tstatistic < Tcritical
Tcritical : - 2.045
-2.722 < - 2.045 ; We reject the Null
Using the α - level (confidence interval) 0.05
The Pvalue for the data from Tstatistic calculator:
df = n - 1 =. 30 - 1 = 29
Pvalue = 0.0108
Reject H0 if :
Pvalue < α
0.0108 < 0.05 ; Hence, we reject the Null

This may help you
he functión Cot[x/2] is not continuos in the points
<span>x=2nπ, where n=0,1,2,3,...</span>
You can check it with a calculator. So the function is not continuos in
the domain the problem gives you, so the Rolle's theorem can not be
applied. If the inteverval was,
<span>[π/2,3π/2]</span>
Then we could apply the Rolle's theorem.
Answer:
3.5
Step-by-step explanation:
Answer:
In point number 3 the angles shown are alternate angles and in point number 4 it is saying that the lines PQ and SR are equal. In point 5 it is saying that the two triangles SRT and QPT are equal because of A. A. S. axiom from statement 3 and 4.
