serious [3.7K]

Answer:

Sara expect the better grade for Math class.

Step-by-step explanation:  

Consider the provided information.

On the Math exam, the mean was µ = 30 with s = 5, and Sarah had a score of X = 45.

Z score for Math: Z=\frac{x-\mu}{s}

Z=\frac{45-30}{5}

Z=\frac{15}{5}

Z=3

On the Spanish exam, the mean was µ = 60 with s = 8 and Sarah had a score of X = 68.

Z score for Spanish: Z=\frac{x-\mu}{s}

Z=\frac{68-60}{8}

Z=\frac{8}{8}

Z=1

On the English exam, the mean was µ = 70 with s = 8 and Sarah had a score of X = 70.

Z score for English: Z=\frac{x-\mu}{s}

Z=\frac{70-70}{8}

Z=0

We can observe that Z score of Math is greater than Spanish and English.

Which means that Sarah did the best in her Math exam.

Hence, Sara expect the better grade for Math class.
