Step-by-step explanation:
Given : The reading speed of second-grade students in a large city is approximately normal, with a mean of words per minute (wpm) and a standard deviation of wpm.
Let x be the random variable that represents the reading speed of second -grade students.
z-score :
For x= 96 words per minute
Now, the probability a randomly selected student in the city will read more than 96 words per minute will be :-
Hence, the probability a randomly selected student in the city will read more than 96 words per minute = 0.2743
