Answer:

The mean is 0.54 and the standard deviation is 0.0135.

Step-by-step explanation:

i) the mean of the sampling distribution is 0.54

iii) therefore for the sampling distribution, q = ( 1 - 0.54) = 0.46

iv) the sample size of the distribution, n = 1356

v)  the\hspace{0.1cm} standard\hspace{0.1cm}  deviation\hspace{0.1cm}  s = \sqrt{\frac{p\times q}{n} }  = \sqrt{\frac{0.54\times 0.46}{1356} } = 0.0135

Last week 40 fifth graders went on a field trip to the science museum.
Artist 52 [7]
PART ONE:
To put this information into a fraction you write part over whole:
 8/40

To change this into a decimal you have to plug in 8÷40 into your calculator:
0.2

PART TWO:
After you subtract 8 from 40, there are 32 fifth graders left.
The fraction will look like this:
32/40

To change this into a decimal you have to plug in 32÷40 into your calculator:
0.8

I hope this was helpful!
