Resistors are labeled 100 Ο. in fact, the actual resistances are uniformly distributed on the interval (95, 103). find the mean resistance. find the standard deviation of the resistances. find the probability that the resistance is between 98 and 102 Ο. suppose that resistances of different resistors are independent. what is the probability that three out of six resistors have resistances greater than 100 Ο?

Now, martin can reasonably guess that the standard deviation for the entire population of people at the mall during the time of the survey is $1.50. what is the 95% confidence interval about the sample mean? interpret what this means in the context of the situation where 95 people were surveyed and the sample mean is $8. use the information in this resource to construct the confidence interval.

Nielsen media research wants to estimate the mean amount of time (in minutes) that full- time college students spend watching television each weekday. find the sample size necessary to estimate the mean with a 15-minute margin of error. assume that a 95% confidence level is desired. also assume that the population standard deviation is known to be 112.2 minutes.
