<span>In a normal distribution 68.27% of the values are within one standard deviation from the mean, 95.5% of the values are within two standard deviations from the mean, and 99.7 % of the values are within three standard deviations of the mean
With that you have the answer to the three questions:
</span>
<span>a. significantly high (or at least 2 standard deviations above the mean).
99.5% of the values are within 2 standard deviations from the mean, half of 100% - 95.5% = 4.5% / 2 = 2.25% are above the mean, so the answer is 2.25%
b. significantly low (or at least 2 standard deviations below the mean).
The other half are below 2 standard deviations, so the answer is 2.25%
c. not significant (or less than 2 standard deviations away from the mean).
As said, 95.5% are within the band of two standard deviations from the mean, so the answer is 95.5%.

Answer:
Three of those boxes equals 27, you would take 27/3 to find out that each box is worth 9. You now want to take 9*4 to get your total number
9*4=36
So 3/4 of 36 is 27
Step-by-step explanation:
Answer:
- x + 75 = 180, as these two angles form a straight angle.
- x = 180° - 75° = 105°
<u>y and x are supplementary angles as p is transversal of l and m:</u>
- y + x = 180°
- y = 180° - x = 180° - 105° = 75°
<u>z is same as 86° as vertical angles:</u>
<u>w and z are supplementary angles as g is transversal of l and m:</u>
- w + z = 180°
- w = 180° - z = 180° - 86° = 94°
if you wrote the problem exactly the way it is asked, there are 10 dogs in the shelter. that's only an approximation...because you can't have half a dog
