Answer:
Step-by-step explanation:
Confidence interval is one which has centre as mean. The width of the interval would be 2 times margin of error.
Margin of error = Critical value * Std error/sq rt of sample
Hence if margin of error is lower for same n, then it means lower confidence level. Option a is right
Similarly, if bigger the sample size, lower is margin of error . Hence option b is right
c) False. Smaller samples make margin of error big and hence confidence intervals bigger.
d) If n becomes 9n, then margin of error becomes 1/3 Hence option d is right.
Answer:
16m, 64m, 144m
Step-by-step explanation:
d=16t²
t=1 t=2 t=3
d=16×1² d=16×2² d=16×3²
d=16×1 d=16×4 d=16×9
d=16m d=64m d=144m
Answer:
160 machines
Step-by-step explanation:
If they can produce 20 machines in one hour, and they work 8 hours on weekdays, all you'd have to do is multiply 20 machines by 8 hours.
The inequality is 5 explanation
