Math Problem Statement
1.2 The data below shows mature age numeracy test scores (%) of a random sample of 28 mature age test candidates at NUST last year: 65 70 78 65 50 99 55 76 58 81 88 70 63 77 50 65 55 78 91 95 56 54 70 76 54 70 86 84 Assume that test scores are normally distributed. 1.2.1 Compute the point estimate of the average score of all candidates who wrote the test. [3] 1.2.2 Construct a 95% confidence interval estimate of the true population mean of candidates scores in the numeracy test. [6
