Remember to follow PEMDAS. First, divide 18 and 2, and multiply 7 with 3 18/2 = 9
7 × 3 = 21 Finally, add
9 + 21 = 30 30 is your answer Hope this helps
Answer:
6

Step-by-step explanation:
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.
