Answer:
The probability that the experimenter’s point estimate of p will be within the interval (0.62, 0.64) is 0.72
Step-by-step explanation:
To find a probability for the confidence interval we need to calculate z-statistic of the margin of error of the confidence interval.
margin of error for (0.62, 0.64) with p=0.63 is 0.01
Margin of error (ME) can be calculated using the equation
where
- z is the corresponding statistic for the given confidence level
- p is the probability of obtaining a head(0.63)
- N is the sample size (300)
Then solving 
gives z≈0.3587
two tailed p-value for z≈0.3587 is 0.72.
Thus, the probability that the experimenter’s point estimate of p will be within the interval (0.62, 0.64) is 0.72
X=12 because say if we choose the base line as our example then the baseline for the small triangle is 7 and the baseline for the bigger triangle is 28. To get from 7 to 28 you have to times by 4 , so the triangle has been enlarged by 4. If we get the side where it says 25 (for the smaller triangle) we can times it by 4 to get 100. Our equation is now 100=6x+28. To work this equation out you do -28 for both sides which equals to 72=6x.
Then we divide by 6 on both sides to get our answer as 12=x
Hope this helped, ask me if you are confused by anything that I just said.
Answer:
well the sum of all the fraction combined are 2.05, so you could fill 2 1/2 drawers. So technically you could use 3 drawers, but the 3rd one won't be full.
hope that helps
