Answer: 0.025
Step-by-step explanation:
Given : A statistics professor plans classes so carefully that the lengths of her classes are uniformly distributed between interval : [48.0 minutes, 53.0 minutes]
Let x be the lengths of her classes that are uniformly distributed between interval : [48.0 minutes, 53.0 minutes].
The probability density function for the given situation :-
The probability that a given class period runs between 51.25 and 51.5 minutes is given by :-
Hence, the probability that a given class period runs between 51.25 and 51.5 minutes is 0.025 .
