Novosadov [1.4K]
Based on the given description above, I have analyzed it and come up with a solution to get the probability if in a random sample of 25 students from this said group and the average height is between 73 and 75 inches. So if you calculate it, it will be like this: 
<span>2P(Z<2)−1</span> To find the probability of Z, use the normal distribution table.
The value for Z being less than 2 is 0.9772. The final result is then<span><span>2(0.9772)−1=0.9544
Hope this is the answer that you are looking for.</span></span>
