The variations in the number of units managed by operators A and B are the same. The average number of units managed per day and the sample variance for operator A and B were obtained, after having observed them for 16 and 21 days, respectively.

What is the probability that the sample variance ratio exceeds 0.52 assuming that the numbers of units handled per day by the two operators are two independent random variables that follow an approximately normal distribution.
