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:
Step-by-step explanation:
x²-8x-20
=x²-10x+2x-20
=x(x-10)+2(x-10)
=(x-10)(x+2)
second factor is x+2
Answer:
5x feet
Step-by-step explanation:
it is 5x because you got to take away the x and just add them together then and the x to the soultion you get
