Because n > 30, the sampling distribution of the mean ages can be approximated by a normal distribution with mean µ and standard deviation σ ÷ √(45) .The central limit theory applies whenever n > 30. Because n > 30, the sampling distribution of the mean ages can be approximated by a normal distribution with mean µ and standard deviation σ ÷ √(n) .
Answer:
319 miles.
Step-by-step explanation:
Original position was let's say 40 yard line.
You must get to the 50 yard line for a first down.
Losing 26 1/3 yardage, you are at the 13 2/3 location
You would need (36 1/3) to get to the 50 yard line.
Wouldn’t it be 60? 60 has both 12 and 15 as factors and is less than 100. 12 x 5 = 60 and 15 x 4 = 60.
