dataset 1 You will need the same dataset used for problem 3 in homework 1 obtained from the yahoo website with the company you selected Use Excel to calculate the average and standard deviation of the close data column Assume that these two numbers represent the population parametric mean and population standard deviation respectively for the variable length in cm in a population of a species of fish Attach a printout of the data to your homework and write down the ticker code on it 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 12 Tesla T SLA Dec 1 365 00 Dec 8 Question 3 356 32 Decis 32533 Decal 312 84 Dec 28 Dec 2 361 53 Dec 9 334 60 Dec 3 33832 Dec 16 Dec lo 339 01 305 97 DEC 27 Dec 29 36706 362 82 and with Comfoonnor Dec 16 336 34 Dec 13 32214 310 86 Dec 23 355 67 Dec 30 356 78 Dec 7 350 58 Dec 14 319 50 Dec 20 299 98 Dec 27 36416
