Using z-scores, it is found that the correct option is:

c. Candace is relatively taller because she has a larger Z-score.

In a normal distribution with mean \mu and standard deviation \sigma, the z-score of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

  • It measures how many standard deviations the measure is from the mean.  
  • After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.

For the z-score of Lebron's height, we have that: X = 81, \mu = 78, \sigma = 2.7, hence:

Z = \frac{X - \mu}{\sigma}

Z = \frac{81 - 78}{2.7}

Z = 1.11

For the z-score of Candace's height, we have that: X = 76, \mu = 69, \sigma = 3.2, hence:

Z = \frac{X - \mu}{\sigma}

Z = \frac{76 - 69}{3.2}

Z = 2.19

Due to the <u>higher z-score</u>, Candace is relatively taller, hence option c is correct.

To determine the density of grains, a student uses a 50ml beaker graded by 5ml increments and a scale with 1g absolute uncertain
labwork [276]

Answer:

The mass of the grains = 120 ± 1 g

Step-by-step explanation:

we are given the following:

Total mass of container + grains = 185 grams

Mass of container = 65 grams

Therefore, mass of grains is calculated as follows:

Mass of grains = ( Mass of container + grains) - mass of container

= 185 - 65 = 120 grams.

since the scale has an absolute uncertainty of 1 g, the mass of the grains is written as 120 ± 1 g
