Answer:
<h2>
11.2≤
12.8 </h2>
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:
The converse of a mid-point theorem states that "if a line is drawn through the midpoint of one side of a triangle, and parallel to the other side, it bisects the third side”
It is already simplified because there is nothing you can divide into both 18 and 25 that would result in whole numbers.
The Probability of him getting green is 4/10 which is 2/5
Answer: The answer is -24 if you start at 0 points
Step-by-step explanation:
3 x 8 = 24 if it starts at zero put a negative symbol (-) to 24.
