Answer:
Step-by-step explanation:
When taking 100 samples of size 30 or greater from a population, exactly 95 of them will create a confidence interval that contains the true population mean. True or false?
This statement is false, or better still, ambiguous. 100 samples of size 30 (or greater) each, means 300 total and it can't be just 95 of them that will contain the true population mean.

Answer:
250
Step-by-step explanation:
They make 2,500 in 5 hours
2500/5 = 500
They 500 in 1 hour
500/2 = 250
250 in 30 mins
Answer:
11 and 2/3.
Step-by-step explanation:
6 and 3/12 = 72/12 + 3/12 = 75/12.
5 and 5/12 = 60/12 + 5/12 = 65/12.
75/12 + 65/12 = 140 / 12 = 70 / 6 = 35 / 3 = 11 and 2/3.
Hope this helps!
Answer:
B. The statement is false because -5 is to the left of -3 on a number line.
Step-by-step explanation:
Statement: -5 > -3
A number line system is a method of locating and expressing the position of directed numbers. It has its middle mark as zero, so that all numbers to the left of zero are less than zero and all numbers to the right of zero are greater than zero.
Comparing two directed numbers -5 and -3. It can be observed that -3 is greater than -5, so that -5 is to the left of -3 on a number line.
Thus -5 > -3 is false.
