Answer:
∠ 1 = 20 x + 5
∠ 2 = 24 x - 1
If lines l and m are parallel:
∠ 1 + ∠ 2 = 180°
20 x + 5 + 24 x - 1 = 180
44 x + 4 = 180
44 x = 180 - 4
44 x = 176
x = 176 : 44
x = 4°

The z-statistic can be calculated as the difference in the population mean and sample mean divided by the standard error. The standard error can be calculated as the standard deviation divided by square root of sample size. The standard error:
SE = 12/ sqrt(20) = 2.68
The z-statistic: (195 -208) 2.68 = -4.86
