The fish in the video Animal Crossing: New Horizons also have differently sized shadows. There are 13 fish with the smallest shadow size, 17 fish with a “small” shadow, 2 fish with a “narrow” shadow, 13 fish with a “medium” shadow, 12 fish with a “large” shadow, and 9 fish with an “extra large” shadow size, 14 fish with the “largest” shadow size.
Suppose you catch two different kinds of fish in this game. What is theprobability that they both have a “largest” shadow size? Round your answer to the nearest ten-thousandth.

At the end of the training, each animal was taken into a room with the handler and a bowl of meat. The dog was hungry, but the handler prevented it from eating for three minutes by squirting the animal with a water bottle and saying “No!” After this period of restraint, the handler left the room, and the length of time it took the dog to begin to eat the meat was recorded. Was the time taken to eat significantly different for different breeds? which of the fllowing is the correct design negotiation CR-2 CR-3 CR 4 CR 5 or CR 25Question 2 The past records of a supermarket show that its customers spend an average of $65 per visit at this store. Recently the management of the store initiated a promotional campaign according to which each customer receives points based on the total money spent at the store, and these points can be used to buy products at the store. The management expects that as a result of this campaign, the customers should be encouraged to spend more money at the store. To check whether this is true, the manager of the store took a sample of 12 customers who visited the store. The following data give the money (in dollars) spent by these customers at this supermarket during their visits. 88 69 141 28 106 45 32 51 78 54 110 83 Assume that the money spent by all customers at this supermarket has a normal distribution. Using the 5% significance level, can you conclude that the mean amount of money spend by all customers at this supermarket after the campaign was started is more than $65?
