Let k be the number of successes (green) when
the spinner is spun 4 times. The graph shows the
distribution of k. Slide the slider to change p. What
effect does this have on the distribution? Check all
of the boxes that apply.
The graph is always a binomial distribution.
No matter what p is, k can always be 0, 1, 2,
3, or 4.
For values of p close to 0.5, the distribution is
more symmetric.
For values of p close to 1, you're most likely
to get 3 or 4 successes in 4 spins.

The larger of two number is 4 less than twice the smaller number. the sum is 41. find the numbers

Asequence is defined recursively using the formula f(n + 1) =f(n) - 5. which sequence could be

3.17 scores on stats final. below are final exam scores of 20 introductory statistics students. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 57, 66, 69, 71, 72, 73, 74, 77, 78, 78, 79, 79, 81, 81, 82, 83, 83, 88, 89, 94 (a) the mean score is 77.7 points. with a standard deviation of 8.44 points. use this information to determine if the scores approximately follow the 68-95-99.7% rule. (b) do these data appear to follow a normal distribution? explain your reasoning using the graphs provided below.
