Suppose that in a dial-up connection you may be connected through one of three types of channels withvarying quality of transmission. In Type I the channel has an error probability of 0.01, in Type Il thechannel has an error probability of 0.005, and in Type III the channel has an error probability of 0.001.Suppose we assume that for the service provider used, 20% of the channels are of Type I, 30% of thechannels are of Type II and 50% of the channels are of Type II.a. What is the probability of error for an arbitrary connection? (Hint: This is similar to the resistorswith the nominal value problem)b. Suppose we observe an error, what is the probability that we were connected via a channelType I?

Parents with young children are convinced that supermarkets place high-sugar cereals on shelves that are at eye-level with children. This strategy supposedly increases the likelihood that mom or dad will be forced to silence a whining child by placing the cereal box with the pirate or bunny rabbit on the front in the grocery cart. The data shown below indicate a cereal's shelf location with values 1, 2, or 3 where 1 is the lowest shelf; shelf 2 is the shelf level most likely to be at a child's eye level; and shelf 3 is the highest. Here we are interested in doing an ANOVA with only 1 factor (shelf height) that has 3 levels. Below you find the unstacked data which includes the sugar content and self height.

A study at the physics laboratory at İstanbul Kültür University is made to examine the defects in an electronic component. The findings reveal that there are four possible types of defect and three types of materials used in those electronic components. The following data have been observed in the laboratory: Material Defect Type Туре I II III IV A 22 45 19 7 B 9 18 8 6 C 16 28 11 10 Test whether the type of defect and type of material are independent from each other or not (Use a significance level of 0.01).
A U-shaped component is to be formed from the three parts A, B, and C. See figure below. The length of A is normally distributed with a mean of 10 mm and a standard deviation of 0.1 mm. The thickness of parts B and C is normally distributed with a mean of 2 mm and a standard deviation of 0.05 mm. Assume that all dimensions are independent. (a) Determin the mean and standard deviation of the lenght of the gap D. (b) What is the propability that the gap D is tess than 5.9mm?
2. You operate a polar research station; every morning, you send a radio message indicating which way the wind is blowing. The wind is likely to blow in any of 4 directions, which you indicate with the codewords "000", "110", "101", and "011". Due to the extreme weather, each bit (0 or 1) of the message independently has a chance of being flipped in transit: 1 changed to 0 or vice versa. What is the probability that when you send your message, the recipient receives "111" on their end?
