Serum cholesterol levels of 100 hypertensive patients were recorded. Mean cholesterol level was 190 mg/d1. The data was symmetri
xxTIMURxx [149]

The standard error is 1.5.

The range of 95% confidence interval is 160 mg/dL and 220 mg/dL

<h3>What is the standard error of the distribution?</h3>

The standard error of the distribution is calculated as follows:

  • Standard error = standard deviation/√N

where N is the number of participants = 100

From the empirical rule of a normal or symmetrical distribution;

  • 68% of the data lies within one standard deviation
  • 95% percent within two standard deviations, and
  • 99.7% within three standard deviations from the mean.

Therefore,  175 mg/dl and 205 mg/dl lie one standard deviation from the mean.

One standard deviation = 175 - 190 or 205 - 190 = ±15

Standard deviation = 15

a. Solving for the standard error using the equation above;

Standard error = 15/√100

Standard error = 1.5

b. The range of 95% confidence interval is two standard deviations away from the mean.

Range of values two standard deviations from the mean = 190 - (2*15) and 190 + (2 * 15)

Range of values two standard deviations from the mean = 160 mg/dL and 220 mg/dL

Therefore, the range of 95% confidence interval is 160 mg/dL and 220 mg/dL

In conclusion, the standard error is calculated from the standard deviation and the sample size.

The ratio of the amount of vitamin A in cow milk to the amount of vitamin A in goat milk is
miv72 [106K]

Answer:

2080 IU

Explanation:

Given

Ratio of vitamin A in cow milk to goat milk = 3 : 4

Required

Determine the content of vitamin A in goat milk if cow milk has 1560 IU

The given parameters shows a direct proportion.

Let G represents Goat and C represent Cow

Given that there exists a direct proportion;

C = K * G where K represents the constant of proportionality.

Solving for K when C = 3 and G = 4

C = K * G becomes

3 = K * 4

3 = 4K

Divide through by 4

¾ = K

K = ¾

Now, solving for G given that C = 1560IU;

We'll make use of the same formula as above

C = K * G

Substitute 1560 for C and ¾ for K; the expression becomes

1560 = ¾ * G

Multiply both sides by 4

4 * 1560 = 4 * ¾ * G

6240 = 3 * G

Multiply both sides by ⅓

⅓ * 6240 = ⅓ * 3 * G

2080 = G

G = 2080

Hence, the vitamin A in the goat milk is 2080IU

What are the similarities between jazz and blues
storchak [24]
Jazz and blues are both characterized by the use of “blue” notes, swung notes, and syncopated rhythms. When blues musicians begin heavily improvising, the line between blues and jazz begins to diminish. In fact, mastery of blues style playing is considered part of learning to play jazz.
