Hi, i'm david and i'm here to help you answer your question.
00:04
Now let me pick up your question here.
00:06
In the question here, when you discuss about the sampling distribution of the sample proportion, let me remind you that if n is large, and then the sample proportion p.

Heart will be approximately to the normal, with the mean it will equal to the population proportion, and the standard division on the phex equals to the square root of the p times 1 minus b, divided by n.
00:33
In the question here we're given the sample n equals to the 400 and we have given the p it will be 22 % contained orange candies so p equal to the 0 .22 from here we can say that the p heart will be approximately the normal with the mean not be hot equal to the p standard division of b equal to the square root of the p times 1 minus b divided by n and then we get equal to the 0 .0207.
01:19
And now we are ready to find the probability that the phech will be greater equal to the 0 .26.
01:26
We know if we take the b heart, we will minus the mean divided by the standard deviation.
01:36
We will obtain the standard normal...
