Compute the variance and standard deviation using the random value that you solved for in the prior question. E(X)= use the value you determined in the prior question. (See the example in the text on Pg. 57 for how to set-up and calculate the outcomes, problem 2-6). Variance =i=15(XiE(X))2P(xi) =variance The variance = Blank 1 The standard deviation = Blank 2. Blan Blank: Professor Mo makes banana pudding on the side. Her banana podding was recently discovered by a popular restaurant in the area. The restaurant would like to 5 ign a contract with Prof, Mo for 30 banana puddings a week at 5100 each ( 512,000/m onth). if 30 banana puddings are not delivered in a week, there is a significant financial penalty (up to 54,000 ) that Prot. Mo would have to pay the restaurant if delivery is missed. Help her determine if she should sign the contract. What is the probability that Prof. Mo will be able to make 30 banana puddings every week? The mean(average) time to make 30 banana puddings is 5 days, and the standard deviation (how many days past 5 days on average) is 2 days. Step 1: Convert the normal distribution to a standard normal distribution (calculate the 8 of standard deviations) if in 5 days and o-2 and we are interested in flnding the probabulity that the random variable X is less than 7 , we want P(xX= watue of the rondom varioble -hean of the distribution a standard deviation Zenumber of standard devations from X to the mean. 2(x4)= The calculated 8 of standard deviations =2/2. Step 2. Look up the probability from a table of normal curve areas. (Table 2.9, pg. 48) tet's look up the value you just computed. What number did you locate? Blank 2 If the mean(average) days to make 30 banana puddings is 5 days, with a standard deviation of 2 days, the probability that Prof. Mo will finish making 30 banana puddings in 7 days is Blank 3% (*only put the value +1 number after the decimal, for example if yout answer is 35.6 ; do not include the 96 sign in your answer).
