Answer:
0.5613
Step-by-step explanation:
Here mean strain of bacteria x = sum of all numbers/ total numbers = 0.5514 %
Standard deviation s = 0.0040 %
Test statistic
G = (x_{max} -x)/s = (0.5613 - 0.5514)/ 0.0040 = 2.475
95% confidence value for outlier for n = 8 and alpha = 0.05
G_{critical} = 2.1266
so here we see that G > G_critical , so we reject that the there is no outlier . the value of 0.5613 is and outlier.

Answer:
Step-by-step explanation:
15, 30, 45, 60 ... (15 + (n - 1)*15 ) ...
n = 5
15 + (5 - 1)*15
15 + 4 * 15
15 + 60
75
n = 6
15 + (6 - 1)*15
15 + 5*15
15 + 75
90
n = 7
15 + (7 - 1)*15
15 + 6*15
15 + 90
