hcc.instructure.com/c + 5 Details The size of fish is very important to commercial fishing. A study conducted in 2012 found the length of Atlantic cod caught in nets in Karlskrona to have a mean of 49.9 cm and a standard deviation of 3.74 cm. Assume the length of fish is normally distributed. A sample of 17 fish was taken. It is possible with rounding for a probability to be 0.0000 a) Identify the individual, variable, type of variable and the random variable X in the context of this problem. The individual is Select an answer The variable information collected from each individual is Select an answer This variable is a Select an answer variable. The random variable X is as follows: Select an answer b) List the givens with the correct symbols. ? ~ = 49.9 cm ? v = 3.74 cm ? v = 17c) Identify the random variable A this problem. Select an answer d) Find the mean of the sampling distribution of the sample mean. Put the numeric value in the first box and the correct units in the second box. e) Find the standard deviation of the sampling distribution of the sample mean. Put the numeric value rounded to two decimal places in the first box and the correct units in the second box. f) What is the shape of the sampling distribution of the sample mean? Select an answer Why? Check all that apply: population is normal On is at least 30 On is less than 30 Oo is unknown Do is known population is not normal 111 O Kg) Find the probability that the sample mean length of the 17 randomly selected Atlantic cod is less than 51.5 cm. Round final answer to 4 decimal places. DO NOT use the rounded standard deviation from part e in this computation. Use the EXACT value of the standard deviation with the square root. h) Find the probability that the sample mean length of the 17 randomly selected Atlantic cod is more than 52.03 cm. Round final answer to 4 decimal places. DO NOT use the rounded standard deviation from part e in this computation. Use the EXACT value of the standard deviation with the square root. i) Is a mean length of 52.03 cm unusually high for 17 randomly selected Atlantic cod? Select an answer j) If you found a mean length for a sample of 17 Atlantic cod as high as 52.03 cm, what might you conclude? Select an
