Answer:
Correct choice is B
Step-by-step explanation:
For the numbers -1 and 59, find the difference 59-(-1):
since 59-(-1)=60 and
(two arithmetic means tells you there will be three intervals), two arithmetic means will be
The only correct sequence is -1, 19, 39, 59.
40 hours at 10.10 per hour = 404
10.10 x 1.5 = 15.15 overtime pay per hour
15.15 x 8 = 121.20
404 + 121.20 = $525.20 total
Answer:
the x axis is the one that lies flat horizontal this is called the run. the y intercept is the one that goes up and down standing. now you have to plot a dot on the line x moving toward the negative 1 and go up to y meeting up to 4 and that should give you the line to graph
Answer:
15:7
Step-by-step explanation:
you put the numbers in order first the number of on time trains to off time trains
Answer:
The probability that the sample mean would differ from the population mean by more than 2.6 mm is 0.0043.
Step-by-step explanation:
According to the Central Limit Theorem if we have a population with mean μ and standard deviation σ and appropriately huge random samples (n > 30) are selected from the population with replacement, then the distribution of the sample means will be approximately normally distributed.
Then, the mean of the distribution of sample mean is given by,

And the standard deviation of the distribution of sample mean is given by,

The information provided is:
<em>μ</em> = 144 mm
<em>σ</em> = 7 mm
<em>n</em> = 50.
Since <em>n</em> = 50 > 30, the Central limit theorem can be applied to approximate the sampling distribution of sample mean.

Compute the probability that the sample mean would differ from the population mean by more than 2.6 mm as follows:


*Use a <em>z</em>-table for the probability.
Thus, the probability that the sample mean would differ from the population mean by more than 2.6 mm is 0.0043.
