Answer:
Step-by-step explanation:
In Statistitics whenever we test a hypothesis for testing a statistic, we use confidence interval.
Confidence interval is on either side of an assumed value a margin of error
Margin of error is calculated as critical value * sigma/sqrt of n
Thus we find that whenever n increases, margin of error decreases, thus making confidence interval narrower and thus making probability for accepting null hypothesis a less value.
Thus we find that option C is right.
C. Increasing the sample size decreases the probability because σx decreases as n increases.
Answer:
650 calls
Step-by-step explanation:
so since you have 18$ per month plus 5 cents per call you would do
18+0.5n(n represent the number of calls)= the total fee of $50.50 cents.
thus,now you need to figure out how much the phone calls were without the monthly fee so you would do:
50.50-18=32.50
so 32.50 is the price of all the phone calls
then you divide 32.50 by 0.05 which equals to 650
meaning that n=650
