Answer: ± 1.96
Step-by-step explanation:
Given the following :
Mean (m) time spent = 11.85
Standard deviation = 4 minutes
Since the population of site visits is Normally distributed, Hence, the test statistic will follow a normal distribution :
The test the hypothesis that mean time has changed at 0.05 confidence interval
Normal distributions have a mean value of 0 and standard deviation of 1
Using a two tailed test At 0.05 confidence interval ;
Using the critical value calculator, which in general under normal distributions :
0.05% confidence interval for a two tailed test is
± 1.96
Answer:
y=1/8x+1.25
Step-by-step explanation:
Since it's perpendicular change the slope to the opposite
You have the slope so plug it into the equation y-y1=m(x-x1)
y-(1)=(1/8)(x--2)

Step-by-step explanation:
Answer:
The value of given expression is 3.8.
Step-by-step explanation:
Given:
We need to find the simplified value of given expression using y =14
Solution:
Now we will substitute y =14 we get;
Now using PEDMAS we will first solve the parenthesis we get;
Now we will solve the exponent function we get;
we know that;
So we can say that;
Now we will solve the multiplication operation.
Now we will perform addition operation.
And finally we will perform subtraction operation.
3.8
Hence The value of given expression is 3.8.
