What do you mean by normal distribution? From a batch of 10000, the lifetime of laptop batteries has a normal distribution with a mean of 40 months and a standard deviation of 8 months. What is the probability that a laptop selected at random will have life time (i) more than 50 months? (ii) between
What do you mean by normal distribution? From a batch of 10000, the lifetime of laptop batteries has a normal distribution with a mean of 40 months and a standard deviation of 8 months. What is the probability that a laptop selected at random will have life time (i) more than 50 months? (ii) between 40 and 50 months? [5]
Parameter Value ------------------ Batch size (N) 10,000 Mean (μ) 40 months Standard Deviation (σ) 8 months Required: (i) $P(X 50)$, (ii) $P(40 < X < 50)$ --- A normal distribution is a continuous probability distribution whose graph is a symmetric, bell-shaped curve about the mean. It is fully d...
