Step-by-step explanation:
when y is 0 x is 2 and 4
(2,0) (4,0)
For the faster cyclist, their rate is 20mi/hr
The second one is 10mi/hr
Answer: X = 9
Step-by-step explanation:
You need to solve for x then to check if it's true you
plug the value in x and solve the equation.
Check if the statement is true.
Answer:
The 95% confidence interval is
This interval means that there 95% confidence that the true mean is within this interval
Yes i would agree with my friend because the lower and the upper limit 95% confidence interval for mean points scored at home is greater than 98 points
Step-by-step explanation:
From the question we are told that
The sample size is n = 20
The sample mean is
The standard deviation is
Given that the confidence level is 95% then the level of significance is mathematically evaluated as
Next we obtain the critical value of from the normal distribution table, the value is
Generally the margin of error is mathematically represented as
substituting values
The 95% confidence interval is mathematically represented as
substituting values
