The following are the height (in cm) of 9 college students who will take the PMA entrance examination. Determine the standard deviation,    178, 185, 185, 184, 190, 198, 195, 172, 184

• 7.98

• 8.08

• 7.12

• 6.22

In a distribution with 240 sample size, the variance is 34.78 and the mean is 22.97, what is the value of its standard deviation?

• cannot be determined because the data set is missing

• 5.90

• lesser than the mean but higher than the standard deviation

• 15.49

What type of relationships does a Pearson's product-moment of correlation assess?

• Bi-modal only

• Curvilinear and Quadratic

• Quadratic and Linear

• Linear only

Maximization of objective function in an Linear Programming model means:

• Value occurs at allowable set of decisions

• Highest value is chosen among allowable decisions

• Value is maximized.

• Greatest amount of optimization.

In a certain normal distribution, find the mean μ when 

σ = 5 and 5.48% of the area lies to the left of 78.

• 64

• 86

• 90

• 80

Which of the following best describe an optimization model?
