Answer: 4
Step-by-step explanation:
For given Population standard deviation , the formula to sample size is given by :-
, where z* = Two-tailed critical value.
E = Margin of error.
Given : years
We know that , Critical value for 90% confidence interval : z* = 1.645
Margin of error : E=1.3 years
Then, the minimum sample size required to construct a 90% confidence interval for the population mean will be :-
[Rounded to the nearest whole number.]
Hence, the minimum sample size required = 4
Answer:
im sorry if this is wrong but i think number 4
Step-by-step explanation:
Change the order of integration. The region over which you're integrating can be equivalently described by the set of points in the plane, .
Then the integral becomes
Substitute , :
Answer:
There are now 6.5 ounces in the new bag.
Step-by-step explanation:
To solve this question, take 30% of 5 and add it to the original amount of 5
30% = 0.30
5 * 0.30 = 1.5
5 + 1.5 = 6.5 ounces of candy.
Hope this helps!
