a Calculate the probability of sampling at random a fish that is smaller in size than the value you would obtain by subtracting half the standard deviation from the average x will be equal to 0 2 b Calculate the probability of sampling at random a fish that is greater in size than the value you would obtain by adding half the standard deviation from the average x 0 2 c Calculate the probability of sampling at random a fish that has a size between the two values x 0 2 x 0 2 used in parts a and b respectively d Calculate the 25th and 75th percentiles of fish size for the population using the normal distribution table e Imagine that 5 individuals are sampled at random from this fish population Calculate the probability that the average calculated will be less than the value u 0 3 B2 1 23 st 4 LO 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 A 356 78 362 06 339 0281 362 82 364 65 355 67 336 29 312 84 299 98 310 86 308 97 325 33 319 5 322 14 339 01 334 6 356 32 350 58 336 34 338 32 361 53 365 B fx AVERAGE A1 A21 C Average D E F H Standard deviation
