Statistics and Confidence Interval Calculations AssignmentQuestion 1 of 201.0 PointsAccepted characters: numbers, decimal point markers (period or comma), sign indicators (-), spaces(e.g., as thousands separator, 5 000), "E" or "e" (used in scientific notation).NOTE:For scientificnotation, a period MUST be used as the decimal point marker.Complex numbers should be in the form (a + bi) where "a" and "b" need to have explicitly statedvalues.For example: {1+1i} is valid whereas {1+i} is not. {0+9i} is valid whereas {9i} is not.The percent defective for parts produced by a manufacturing process is targeted at 4%. The process ismonitored daily by taking samples of sizes n = 160 units. Suppose that today’s sample contains 14defectives.Determine a 95% confidence interval for the proportion defective for the process today.Place your LOWER limit, rounded to 3 decimal places, in the first blank. For example, 0.123 would be alegitimate answer.0.044Place your UPPER limit, rounded to 3 decimal places, in the second blank. For example, 0.345 would bea legitimate entry.0.131Question 2 of 201.0PointsAccepted characters: numbers, decimal point markers (period or comma), sign indicators (-), spaces(e.g., as thousands separator, 5 000), "E" or "e" (used in scientific notation).NOTE:For scientificnotation, a period MUST be used as the decimal point marker.Complex numbers should be in the form (a + bi) where "a" and "b" need to have explicitly statedvalues.For example: {1+1i} is valid whereas {1+i} is not. {0+9i} is valid whereas {9i} is not.After calculating the sample size needed to estimate a population proportion to within 0.05, you havebeen told that the maximum allowable error (E) must be reduced to just 0.025. If the originalcalculation led to a sample size of 1000, the sample size will now have to be4000. Place youranswer, as a whole number in the blank. For example, 2345 would be a legitimate entry.Question 3 of 201.0 Points
