This is pure logic, so there is no step-by-step explanation.
Answer: 0.4332
Step-by-step explanation:
PEMDAS
(27^-30) first which is 1.14 I rounded up to the nearest hundredth place and i got my answer 1.14. the secondly you do 2/3 to the power of 1.14 which is 0.4332
<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%.
</span>
28.75 rounded to the nearest whole number would be 29
