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:
Julie made $3 /hour more than Loren
Step-by-step explanation:
Loren makes 18 /2 = 9 ($9 / hour constant ratio)
Julie: 36 /3 = 12 ($12 / hour)
Julie - Loren = 12 -9 = 3
? in Loren's : 126, 144
? in Julie's : 72, 252
Hello,
The normal perpendicular to x-4y+2=4ln(3) or y=(x+2-4ln(3))/4
has as slope -4
So y'=(ln(2x+a))'=1/(2x+a) *2 if x=1 , y'=1/(2+a)
Thus
1/(2+a)=-4 ==>2+a=-1/4==>a=-1/4-2==>a=-9/4
Answer: 2x-7, 2+4.
