Lol no idea look at ur notessssssssss
Let 's' be the allowed speed.
If the maximum speed is 70 and the minimum is 40, we know 's' is between these two values inclusively, i.e. 40 ≤ s ≤ 70
*Remember for inequality symbols, whether strict or inclusive, the term on narrow side is "less than" the term on the broad side
The constant proportionality is whats left over
Answer:
We can select a lower confidence level and increase the sample size.
Step-by-step explanation:
The precision of the confidence interval depends on the margin of error ME = Zcritical * Sqrt[(p(1-p)/n]
In this Zcritical value is in the numerator. Z critical decreases as Confidence level decreases. (Zc for 99% = 2.576, Zc for 95% is 1.96, Zc for 90% = 1.645). Therefore decreasing the Confidence level decreases ME.
Also we see that sample size n is in the denominator. So the ME decreases as sample size increases.
Therefore, We can select a lower confidence level and increase the sample size.
