Answer:
Yes
Step-by-step explanation:
First, suppose that nothing has changed, and possibility p is still 0.56. It's our null hypothesis. Now, we've got Bernoulli distribution, but 30 is big enough to consider Gaussian distribution instead.
It has mean μ= np = 30×0.56=16.8
standard deviation s = √npq
sqrt(30×0.56×(1-0.56)) = 2.71
So 21 is (21-16.8)/2.71 = 1.5494 standard deviations above the mean. So the level increased with a ˜ 0.005 level of significance, and there is sufficient evidence.
Answer:
$450
Step-by-step explanation:
A way to find the median of a set of numbers is by listing each number one by one and then slowly crossing out the smallest and biggest number one by one. If you end up with two numbers left, then you take the mean of those numbers. To do that, you add the two numbers and divide it by two.
The given equation is

hence

But x cannot be zero so x=3
So the value of x is 3

Hi!
We will find the solution like this:
76 - 53 = 23 that's the difference in numbers, so now we have to find the percentage of this difference related to throwing the ball before strength and conditioning program, like this:
23/53 = 0,434 = 43,4%
The correct answer is B. 43,4%.
Hope this helps!
