Suppose that a simple random sample is taken from a normal population having a standard deviation of 7 for the purpose of obtaining a 95% confidence interval for the mean of the population Complete parts (6) through (c) below Click here to view Page 1 of the table of areas under the standard normal cute Click here to view P2002 of the table of rows under the standard normal.cat CIT a. If the sample size is 9. obtain the margin offro The margle of error for a sample size of 9 (Round to two decimal places as needed) b. Repeat pont (a for a sample size of 36 The margin of error for a sample size of 36h (Round to two decimal places as needed) c. Can you guess the margin of orror for a sample size of 1447 Explain your reasoning The margin of error for a comple size of 164 (Round to wo decimal places as needed) Explain your reasoning Because the sample size Increased by a factor of from part (b) to part(), the margin of error was (Type Whole numbers divided we More
