The scores on a standardized test taken at the University of lowa are normally distributed with a mean of 100 and standard deviation of 10. What test score is 0.1 standard deviations above the mean?You have a really annoying stapler that seems to randomly jam. [in any given attempt to staple. it seems to independently jam 13.?56 of the time. 25!} attempts were made use the stapler. a} Find the mean and standard deviation for the number of jammed staples out of 230 attempts according to the Binomial Distribution. Mean: I I Standard Deviation {rounded to 2 decimals]: I I b] Does the normal approximation apply? Is the success a\" failure condition met [using a cutoff of 5}? {21- No 2:1- Yes c} Use the normal distribution {with continuity correction] to find the probability that your stapler will jam more than as times out of 180 attempts. Use the rounded standard deviation in your calculation. z-score [to 1 decimals} = I I probability [to 4 decimals. using the rounded z-score}
