Answer:
92.9997<
<99.5203
Step-by-step explanation:
Using the formula for calculating the confidence interval expressed as:
CI = xbar ± Z * S/√n where;
xbar is the sample mean
Z is the z-score at 90% confidence interval
S is the sample standard deviation
n is the sample size
Given parameters
xbar = 96.52
Z at 90% CI = 1.645
S = 10.70.
n = 25
Required
90% confidence interval for the population mean using the sample data.
Substituting the given parameters into the formula, we will have;
CI = 96.52 ± (1.645 * 10.70/√25)
CI = 96.52 ± (1.645 * 10.70/5)
CI = 96.52 ± (1.645 * 2.14)
CI = 96.52 ± (3.5203)
CI = (96.52-3.5203, 96.52+3.5203)
CI = (92.9997, 99.5203)
<em>Hence a 90% confidence interval for the population mean using this sample data is 92.9997<</em>
<em><99.5203</em>
Answer:
30.9°
Step-by-step explanation:
Right Angle Triangle = 90°
59.1 + ? = 90
90 - 59.1 = 30.9
Prime factorize the two numbers:
666 = 2 x 3 x 3 x 37
888 = 2 x 2 x 2 x 3 x 37
Notice I lined up all the numbers into columns. If they appear for both numbers they are paired. The lowest common multiple is the product of all the unique columns:
LCM = 2 x 2 x 2 x 3 x 3 x 37 = 2664
You can use this strategy for as many numbers as you want. Also, you could find the greatest common factor by multiplying only the paired columns.
