Candice is preparing for her final exam in Statistics. She knows she needs an 74 out of 100 to earn an A overall in the course.
Salsk061 [2.6K]

Answer:

Hence the correct option is option b) Yes, the upper level of one standard deviation is 72.

A score of 74 is not within one standard deviation of the mean.

Step-by-step explanation:

Here the given details are,

Mean = 68  

SD = 4  

Distribution is normal.  

Z-score for x = 74 is given as below:  

Z = (X - mean)/SD\\Z = (74 - 68)/4\\Z = 1.5  

So, the score of 74 is 1.5 standard deviations from the mean.  

Mean + 1\timesSD = 68 + 1\times4 = 72Mean - 1\timesSD = 68 - 1\times4 = 64  

Therefore the score is not lies between 64 and 72.  

Yes, the upper level of one standard deviation is 72.
