Data in the table below were collected to investigate the relationship between pressure the corresponding scale reading for the purpose of calibration. We fit a model to the data. linear regres Pressure, x 8. 10 8 10 40 50 40 30 Scale Reading, y 18 11 14 15 70 90 72 88 (a) Compute the mean of x data, . (b) Compute the mean of y data, g. (c) 1 = 8,528, 1 y = 26, 794. Compute SSay and SSa. (d) Find the estimated slope b1, and the estimated intercept bo. (e) Give the fitted regression line. (f) What is the estimated scale reading when the pressure is 12? in used to compare four normal population means wit I their data summaries are liste
Percentage
A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.
Algebraic Expressions
In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.
Numbers
Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
Subtraction
Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.
