Answer:
Standard error
Step-by-step explanation:
The standard deviation of the distribution of sample means is called the standard error of the means.
It is denoted by: 
The standard error is calculated using the formula: 
where n is the sample size and 
is the population standard deviation.
Answer:
0.21
Step-by-step explanation:
Given that Jane is a better tennis player than Jack is. If the probability that Jane will beat Jack in any given game is 0.7,
Probability for Jane beating Jack is 0.7 and hence
Probability for Jack beating Jane is 0.3
We find that each game is independent of the other
If two games are played
Probability that they will each win one game if they play two games
= Prob that Jack wins one game * Prob that Jane wins one game
= 0.7*0.3
= 0.21
(Since if A and B are independent events P(AB) = P(A) *P(B)

Answer:
Any set of (x , y) whose distance from (4, -3) is 3 units lies on the circle.
Step-by-step explanation:
To find the distance , use the formula
If distance < 3, (x, y) lies inside the circle.
If distance > 3, (x, y) lies outside the circle.
If distance = 3 (x, y) lies on the circle.

The y-intercept is the y value when x = 0. Another way to reword that is when the graph crosses the y-axis.
Slope-Intercept Form: y = mx + b
- m - slope
- b - y-intercept
Step-by-step explanation:
<u>Step 1: Define</u>
y = 3/4x + 2
<u>Step 2: Break Function</u>
<em>Identify Parts</em>
Slope <em>m</em> = 3/4
y-intercept <em>b</em> = 2
