Answer:
14
Step-by-step explanation:
Given the data:
13 15 14 16 12
The point estimate of the population mean will be :
ΣX/ n
X = Given data points
N = sample size
ΣX = (13 + 15 + 14 + 16 + 12) = 70
N = 5
Hence,
ΣX/ N = 70 / 5
Point estimate of population mean = 14

Paige is ahead of kate. It dosen't say she is behind anyone or last in the line. Carlos is not first in line. Kate cannot be first because someone is ahead of her. And lisa is last. So the answer is definitely paige. Hope i helped. Have a nice day.
Answer:
Step-by-step explanation:
Part 1
P(z < -1.45)
Using the z score table
P =
Part 2
We solve using z score formula
z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
a) P(X >52)
x = 52
Mean = 60
Standard deviation = 8
z = 52 - 60/8
z = -1
P-value from Z-Table:
P(x<52) = 0.15866
P(x>52) = 1 - P(x<52) = 0.84134
b) P(48 < x < 64)
