6 The lengths of female snakes of a particular species are normally distributed with mean 54 cm and standard deviation 6.1 cm .
- Find the probability that a randomly chosen female snake of this species has length between 50 cm and 60 cm .
The lengths of male snakes of this species also have a normal distribution. A scientist measures the lengths of a random sample of 200 male snakes of this species. He finds that 32 have lengths less than 45 cm and 17 have lengths more than 56 cm . - Find estimates for the mean and standard deviation of the lengths of male snakes of this species.
