The value of the discriminant in this equation is (-4)^2-4*1*5 which is -4
Just for reference;
If the value of the discriminant is negative, the equation has no real solution
If the value of the discriminant is positive, the equation has two real solutions
If the value of the discriminant is zero, the equation has one real solution.
Therefore, the discriminant is -4, so the equation has no real solutions

Answer:
And the 95% confidence interval would be between (69.027;80.793)
Step-by-step explanation:
Information given
represent the sample mean
population mean (variable of interest)
represent the population standard deviation
n=33 represent the sample size
Confidence interval
The confidence interval for the mean is given by the following formula:
(1)
The degrees of freedom are given by:
The Confidence level is 0.99 or 99%, the significance would be and , the critical value for this case would be
And replacing we got:
And the 95% confidence interval would be between (69.027;80.793)
