Answer:
<h2>11.2≤Step-by-step explanation:
Confidence interval for the population mean is expressed by the formula;
CI = xbar ± Z(S/√n) where;
xbar is the sample mean = 12.5
Z is the z score at 99% confidence = 2.576
S is the standard deviation = √variance
S = √2.4 = 1.5492
n is the sample size = 25
Substituting the given values into the formula given above,
CI = 12.5 ± 2.576(1.5492/√25)
CI = 12.5 ± 2.576(0.30984)
CI = 12.5 ± 0.7981
CI = (12.5-0.7981, 12.5+0.7981)
CI = (11.2019, 12.7981)
Hence the 99% confidence interval for the population mean is 11.2≤12.8 (to 1 decimal place)
Answer:
all reals except 3 & 4
Step-by-step explanation:
recall you cannot have a 0 in the denominator.
any values of x that would produce a 0 in the denominator are excluded from the domain
factor Factors -3, -4
(x-3)(x-4)
x cannot be 3 or 4
