Question

the lifetime of a certain type of battery can be approximated by a normal distribution. the list gives the number of hours of battery life of 10 batteries selected at random. find the mean and standard deviation of the data set. then sketch a normal curve to represent the distribution. 24, 24, 32, 14, 22, 34, 20, 26, 17, 29

Answer 1

Answer: mean= 24.2 and the standard deviation is 6.0 :)

Step-by-step explanation: this is because when you solve for the equation the result for the standard deviation is 6.3 but if you round the number, it becomes 6.0, being the standard deviation.
