5 and 0 and 8
5thousand 0 hundred 8millionnn
Here, p^ = (0.39 + 0.47)/2 = 0.43
The given interval is (0.43 - 0.04, 0.43 + 0.04).
Therefore, the margin of error is 0.04.
Answer:
the value of x=9 and AB(h)=9.396
Answer:
a. No the null hypothesis cannot be rejected at 1% level of significance as the calculated value of z= 2.222 which lies with in 2.333
b. Yes for the Type 1 Error of 2.5% we say the toaster oven consumes more than 250 W of power because the calculated value 2.22 lies outside the region for 1.96
c. The cut-off at 2.5% level of significance is 258.82 W.
d. 0.85 is the area for Type 2 error.
e. The cut-off at 1% level of significance is 260.485W.
f. 0.154 is the area for Type 2 Error
g. The Type 2 Error is increased when Type 1 Error is decreased.
h. The Type 1 Error is decreased when Type 2 Error is increased .
Step-by-step explanation:
The answer is attached.
