(1 point) Suppose one file of a certain file type (such as an image file at certain settings) has an average size of one megabyte with a standard deviation of half a megabyte. Assume file sizes are independent of each other. What is the probability that 300 such files can fit within 330 megabytes? (A calculator is required.)

Suppose the average lifetime of a certain type of car battery is known to be 60 months. Consider conducting a two-sided test on it based on a sample of size 25 from a normal distribution with a population standard deviation of 4 months. a) If the true average lifetime is 62 months and a=0.01, what is the probability of a type II error? b) What is the required sample size to satisfy and the type II error probability of b(62)...

Suppose for a certain microRNA of size 20, the probability of getting a purine is binomially distributed with a probability of 0.7. There are 100 of these microRNAs, each independent of the other. Let Y denote the average number of purine in these microRNAs. Find the probability that Y is greater than 15.
