• Currently, there is above 150 patients admitted in Amang Rodriguez Memorial Medical Center. About 50% shows moderate symptoms. Another 20% are severe, where they need high-flow oxygen.

Multiple Choice

Currently, there is above 150 patients admitted in Amang Rodriguez Memorial Medical Center. About 50% shows moderate symptoms. Another 20% are severe, where they need high-flow oxygen

which graph is the correct representation of the above 150 patients admitted?

Find the area above z = 150

• Z = 2

Multiple Choice

what the corresponding area of z=2?

• 0.7724

• 0.4772

• 0.3413

• 0.4313

a.   Find the area above z = 150

• Z = 2 corresponds to an area of 0.4772

• 0.5 - 0.4772 = 0.0228

• The proportion of the area above z=150 is 0.0228 or 2.28%

Multiple Choice

a.Show the graph of the percentile in which the patients show moderate symptoms. 50 % moderate

Multiple Choice

a.Show the graph of the percentile in the patients show severe symptoms. 20 % severe

If the 2 weeks of enhanced community quarantine proves to be efficient, it is expected that the number of patients will decline to at most 17% of the previous count. And those who has moderate symptoms could be cut into half which goes down at 10%.

Multiple Choice

In 2 weeks of Ncr bubbles the number of armmc patients decrease below 125. Now find correct graph represents below z= 125

a.   Find the area below z = 125.

• Z =1.00 

Multiple Choice

what is the corresponding area of z =1?

• 0.3113

• 0.3413

• 0.3143

• 0.3141

a.   Find the area below z = 125.

• z=1

• Z =1.00 corresponds to an area of 0.3413

• 0.5 + 0.3413 = 0.8413

• The proportion of the area below z=125 is 0.8413 or 84.13%

Multiple Choice

What is definition of percentile in relation to a normal curve?

• a number or ratio expressed as a fraction of 100.

• it is descriptive measure of the relationship of a measurement to the rest of the data

• the measure of the mean, median and mode

• any value in the z-table multiplied to 100%

Multiple Choice

Why do we use Z score?

• To get the corresponding area of a given z-value

• To get the percentile of the given data

• To solve for the mean of the given set of data.

• To calculate for the mean of the given distribution

Multiple Choice

Whait is a normal curve?

• A parabolic curve in a graph representing data in a quadratic equation.

• A graph of data skewed to the right to represent positive values.

• A graph of data skewed to the left representing negative values.

• A bell-shaped curve used to represent data from a distribution.
