Answer:
Test statistic = -2.44
There is enough evidence to support the strategist's claim.
Step-by-step explanation:
H0 : p = 0.41
H1 : p < 0.41
pˆ = 0.38
Test statistic :
z=pˆ−p/√p(1−p)/n
Z = (0.38 - 0.41) / √(0.41(1 - 0.41) / 1600
Z = - 0.03 / √0.0001511875
Z = - 0.03 / 0.0122958
Z = - 2.4399
Test statistic = -2.44
The Pvalue :
P(Z < -2.44) = 0.0073436
α - level = 0.02
If Pvalue < α ; Reject H0
0.0073436 < 0.02 ; We reject H0
Since Pvalue < α ; Hence, There is enough evidence to support the strategist's claim.
Answer:
In the 3rd and 4th quadrants of the coordinate system
ie π < θ < 2π. At π and 2π the sine values are zero
Step-by-step explanation:
I hope you want to simplify this expression.
To simplify the given expression we can use the order of operation.
So, first step is to operate multiplication. Therefore,
400 x 34 = 13600
Hence,
400x34+23444444444-23444444444
= 13600 +23444444444-23444444444
= 13600 + 0 Since +23444444444-23444444444 = 0
= 13600.
So, the simplified value of the given expression is 13600.
Hope this helps you!.
