For bone density scores that are normally distributed with a mean of 0 and a standard deviation of​ 1, find the percentage of sc
mr Goodwill [35]
<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%.

In​ 2010, there were 12.4 million citizens of a certain country diagnosed with diabetes. This number of cases represents an incr
alukav5142 [94]

Answer:

3,131,313

Step-by-step explanation:

Let X represent the number of cases with diabetes in 1973.

An increase of 396% in diabetes cases in 1973 would be;

12.4 million = 396/100 × X

12.4 million = 396X/100

Cross multiply

12.4 million × 100 = 396X

X = [(12.4 million × 100) / 396]

X = 3,131,313

Therefore, the number of diabetes cases in 1973 is 3,131,313 cases
