Answer:
90% confidence interval for the mean is between a lower limit of 3.08 days and an upper limit of 3.18 days.
Step-by-step explanation:
Confidence interval is given as mean +/- margin of error (E)
mean = 3.13 days
sd = 0.48 day
n = 250
degree of freedom = n-1 = 250-1 = 249
confidence level (C) = 90% = 0.9
significance level = 1 - C = 1 - 0.9 = 0.1 = 10%
critical value (t) corresponding to 249 degrees of freedom and 10% significance level is 1.65153
E = t×sd/√n = 1.65153×0.48/√250 = 0.05 day
Lower limit of mean = mean - E = 3.13 - 0.05 = 3.08 days
Upper limit of mean = mean + E = 3.13 + 0.05 = 3.18 days
90% confidence interval is (3.08, 3.18)
<u>Answer:</u>
<u>Step-by-step explanation:</u>
We are given the following expression and we are to simplify it:
To make it easier to solve, we can also write this expression as:
Now we will cancel out the like terms to get:
Taking the square root of the terms to get:
Answer:
Y= 5/3x -7
Step-by-step explanation:
To find the slope with the given points you find the distance between the y values and the x values. (Rise/Run = Y/X). Once you find the pattern you can use it until you find the y intercept if you're using graph paper!
Hope this helps! :)
(Side Note: The distance for the y values from -2 and 3 is +5. The distance for the x values is +3 )
