Answer:
The function for the model that gives the pressure in atm is given as:
P = 1.000 + 0.030*D
Step-by-step explanation:
From the question, we are given the Depth with corresponding P. Our duty is to calculate the Pressure (P) in the atm given the Depth (D). From this, we know that:
1. Pressure (P) is the dependent variable, and
2. Depth (D) is the independent variable.
Hence the function is a linear relationship which is known as regression equation. This can be achieve by estimating the:
i) Slope (β), and
ii) Intercept (α).
We can obtain the slope by:
, and
.
Hence, the function is:
= α + β D
You can achieve the task through R programming. Here is the R code.

D = c(0,33,66,99,132)
P = c(1,2,3,4,5)
mod = lm(P~D)

Answer:
0.015 is the approximate probability that the mean salary of the 100 players was less than $3.0 million
Step-by-step explanation:
We are given the following information in the question:
Mean, μ =$3.26 million
Standard Deviation, σ = $1.2 million 100
We assume that the distribution of salaries is a bell shaped distribution that is a normal distribution.
Formula:
Standard error due to sampling =
P(mean salary of the 100 players was less than $3.0 million)
Calculating the value from the standard normal table we have,
0.015 is the approximate probability that the mean salary of the 100 players was less than $3.0 million
