Answer: 0.355,0.405)
Step-by-step explanation:
Given : Significance level : 
Number of subjects (n) = 2455
Number of surveys returned = 931
The probability of surveys get return will be :-

The confidence interval for proportion is given by :-


Hence, the 99% confidence interval for the proportion of returned surveys : (0.355,0.405)
<span>Hey there, Lets solve this step by step.
</span>
<span>"Two times the quantity of a number minus 12”
</span><span>Two times the quantity = 2 * n
</span>
<span>number minus 12 = n - 12
</span>
Therefore
2n-12
Answer:
See below ↓
Step-by-step explanation:
The relation is :
- Let y = Motor Speed and x = Voltage
- y = 25x
<u>Title</u> : Variation of Motor Speed with Applied Voltage
<u>x-axis label</u> : Voltage (volt)
<u>y-axis label</u> : Motor speed (rpm)
As it constantly varies with a value of x and they are not isolated data points, they should be connected with a line.
Here u go :) hope it helps
