00:01
So, we are given that records indicate the property of online retails order being fraudulent is 0 .06.
00:15
And supposing that on a given day, 21 online retailers orders are placed.
00:23
So, according to that, for the first part, what is the mean and standard division of the number of online retail orders that we need to find it out here.
00:33
So, according to the question, clearly you can see n is nothing but what the number of orders.
00:38
That is we have been given equals to 21.
00:41
Similarly, p is what property of fraudulent.
00:44
That is we have been given equals to 0 .06.
00:47
So, can we find it out the q? probability of not fraudulent, it will be equals to 1 minus p is equals to 1 minus of 0 .06 is equals to 0 .94.
00:57
So as for the a part, since we need to calculate the mean and standard deviation, so mean can be given by the formula of mean is equals to the n times of p...
