answer to someone who has never taken a course in statistics. Solution: (a) Use the steps of hypothesis testing. Size of sample‚ n = 8 Degree of freedom = n-1 = 8-1 = 7 Sum of sample = i=1∑n=8xi = (25+27+25+23+24+25+26+25) = 200 | Time (in Hours) | Sum | Mean(xm) | (xi- xm)2 | Standard Deviation | 1 | 25 | 200 | Mean = Sum/n= 200/8= 25 | 0 | σ = √( i=1∑n=8(xi-xm)2/(n-1))= √(10/7)= √1.4285= 1.195 | 2 | 27 | | | 4 | | 3 | 25 | | | 0 | | 4 | 23 | | | 4 | | 5 | 24 | | | 1 |
