Assume that a national fitness study reports that 10% of millenials exercise daily. suppose that a researcher surveys a random sample of 250 millenials regarding their daily exercise habits. assume that is a binomial random variable that represents the number of millenials in the sample who exercise daily. compute the mean and standard deviation of the sampling distribution of . report as a whole number and as a decimal precise to two decimal places.

Step-by-step explanation:

Let X be the number of millenials  in the sample who exercise daily

Given that X is binomial with n = 250 and p = 10% = 0.1

q =

As per binomial distribution rule we have

Mean of X = E(X) =

Variance of X =

Std dev=

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.
