Answer:
0.024h
Step-by-step explanation:
We have the equation:
t 10 + t 15 = 0.6
<=> 25t = 0.6
<=> t = 0.024
It means that, it takes 0.024h for two people to complete 60% of the task
I hope it will find you well.
From the given problem the same size is n = 70. Df = n – 1 =
70 – 1 = 69.
The population mean is u = 30, sample standard deviation is
s = 10 and the sample size is n = 70. Then,
t = x – u / s sqrt of n
1.995 = x – 30 / (10 sqrt of 70)
1.995 = x – 30 / 1.1952
X – 30 = 1.995 (1.1952)
X – 30 = 2.3844
X = 30 + 2.3844
X = 32.3844
The sample mean is 32.3844
