When it comes to shelter cat adoptions animal shelters report that black cats are the hardest to find forever homes for. Given a sample mean (xbar) of 46 and a population standard deviation sigma of 2.0 where n= 30, find the z value and p value. The data indicates that the population mean (mu) for black cat adoption during a given year is 50. Test the claim by black cat rescues that it is less than 50. For this problem us .05 as your alpha.

According to IT department of leading financial firm, 50% of emails received by their employees are spam. They are planning to install a software which filters the spam emails. A reputable cybersecurity brand has launched a software which claims to detect 99% of spam emails. However, they have also reported 5% as the chance of detecting a non-spam email as spam. If an email is detected as spam, what is the probability of it in fact being a non-spam email?
A score S is used to predict whether a disease is present. If the score is greater than a threshold value, the corresponding person is classified as ill, otherwise as healthy. Here, the scores S; for 9 persons are given. Furthermore, it is known whether the persons are actually ill (Y, = 1) or not (Yi = 0). The data look as follows: S; | Y; 0.3 0 1.2 1 0.7 0.8 1 0.1 0.4 1 1.1 0 0.2 0 1.4 1 (a) Draw by hand the ROC curve for the given data. Explain your procedure and the calcu- lation methods. (b) Calculate the area under the curve (AUC) by hand. Does this value indicate a good or bad classification? (c) Calculate the partial area under the curve (PAUC) if the specificity is to be at least 0.65. How do you judge this value?
