Question

suppose a certain species of awns between 1 and 5 months old have a body weight that is approximately normally distributed with mean μ = 28.6 kilograms and standard deviation σ. 3.7 kilograms. Let x be the weight of a fawn in kilograms. Convert the following : interval to a x interval. 2.7 <z Select one: a. x< 18.61 b. x>18.61 c, x >-38.59 . d. x < 38.59 e. x>38.59

Answer 1

Answer

We have mean = 28.6, standard deviation = 3.7 and z value = 2.7

z value is less than 2.7

we know the formula

setting given values, we get

multiplying both sides by 3.7, we get

adding 28.6 on each side, we get

we get

so, we can write it as

option e is correct answer
