Answer:
-1.05 -.75p
Step-by-step explanation:
-3(0.15+0.2+0.25p)
Distribute the 3 to each term in the parentheses
-3(0.15)+-3(0.2)+-3(0.25p)
-.45 -.6 -.75p
Combine like terms
-1.05 -.75p
Answer:
Step-by-step explanation:
how we supposed to do it , when we cant control it
1,685 rounded to the nearest hundred would be 1,700 since if we count from right to left, we see ''6'' is in the hundreds column so to round it to the NEXT hundred, I just moved it up a spot and made it 7, and so now its 1,700.
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.
