I'm stuck please help me

The life of a car battery is approximately normal. A manufacturer states that the mean life of a car battery is 50 months with a standard deviation of 7 months. nts i. What is the probability that a car battery is selected and its life is at least 51 months? Round to 4 decimal places, if necessary. If a production manager takes a sample of 25 car batteries, then for this sample size, describe sampling distribution of . ii. Center: H iii. Spread: SET Round to 1 decimal place, if necessary. iv. From the given information what can we say about the shape of the sampling distribution of r? O The distribution of of I is approximately normal because np 2 10 and n(1 - p) 2 10. O The distribution of a is not approximately normal because the population ishot normal. O The distribution of i is approximately normal because the population is normal, so the sampling distribution of any size n is approximately normal. O The distribution of i is approximately normal because the sample size is large, in other words n > 30. O The distribution of is not approximately normal because the sample size is small, in other words n
