Answer: ($3.055, $3.205)
Step-by-step explanation:
Given : Significance level : 
Critical value : 
Sample size : n= 36
Sample mean : 
Standard deviation : 
The confidence interval for population mean is given by :_
Hence, the 95% confidence interval to estimate the population mean = ($3.055, $3.205)
Type the equations to a website called maths papa-using their algebra calculator, i highly recommend it, it shows all the working clearly and the answers are always correct

True!
Step-by-step explanation:
If an object travels at a constant speed, then the distance traveled is directly proportional to the time spent traveling, with the speed being the constant of proportionality. The circumference of a circle is directly proportional to its diameter, with the constant of proportionality equal to π.
Answer:
The correct answer is option C that is graph X.
Step-by-step explanation:
Given : 1 sack lunch has 3 sandwiches
x axis = Number of sack lunches
y axis = Number of sandwiches
The coordinate from the given data will be: (1,3)
So, from the given graphs the graph with coordinate point (1,3) is correct. It will also show change in number of sandwiches with respect to change in number of sack lunches.
