Hi there.
00:01
So for this problem, we need to calculate the point estimate, the margin of error, and the confidence interval step by step.
00:08
So the first thing that we are going to calculate is the point estimate.
00:14
Okay.
00:15
So the point estimate will be pithad, which is the number of successes, which in this case is 58 divided by the number of the sample size, which is 100.
00:24
So this will give us 0 .58.
00:27
So this will be the point estimate.
00:31
Now, for part two of this problem, we're asked about the critical seed score.
00:36
Now, for a 95 % confidence, okay, interval, the critical seat correspond to at a 95 % confidence level, using a seat table, you can just find this value to be 1 .645, and that will be the solution for part two of this problem.
01:00
Now for part three, we are asked about the margin of error.
01:05
Now, the margin of error formula is as follows.
01:10
The seed critical value that we obtain, now times p hat, time 1 minus p hod, then this divided by m.
01:19
And then the values are the ones that we just determined in n, which is 100 for this...
