Please help with D. Thanks! Let X denote the courtship time for a randomly selected female-male pair of mating scorpion flies (time from the beginning of interaction until mating).

Condition- and Status-Dependent Courtship Decisions in the Scorpion Fly Panorpa Cognate"t).In USE SALT(a) Is it plausible that X is normally distributed?O Yes, courtship time is plausibly normally distributed. Since X must be negative, realistically the interval u + 3ơ should be entirely negative which is true in this case.O Yes, courtship time is plausibly normally distributed since the mean of X is larger than 100.O No, courtship time cannot plausibly be normally distributed.
