13. Provide an appropriate response. Samples of size n= 60 are randomly selected from the population of numbers (O through 9) produced by a random-number generator, and the mean is taken for each sample. What is the distribution of the sample means? O not enough information provided O normal (approximately) O skewed to the right O skewed to the left

true? is that what you're asking or do you mean something else?

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
