Answer:
The value of test statistic
|Z| = |-2.2883| = 2.2883
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the mean of the Population = 57.7miles/gallon
The standard deviation of the Population = 1.9
The mean of sample x⁻ = 57.4
Given that the sample size 'n' =210
level of significance = 0.1
<u><em>Step(ii):-</em></u>
Test statistic


Z = -2.2883
|Z| = |-2.2883| = 2.2883
<u><em>Final answer:-</em></u>
The value of test statistic
|Z| = 2.2883
Answer:
-12p ^4
Step-by-step explanation:
4p^3 * -3p
-3 * 4 = -12
p^3 *p
use the math rule :
a^n * a^m = a^(n+m)
therefore
p^3 * p^1 = p ^(3+1)
= p^4
= <u>-12p ^4</u>
Answer:
hii there
The correct answer is ( D )
hope it helps you
have a nice day
