A random sample of 45 door-to-door salespersons were asked how long on average they were able to talk to the potential customer.
dimulka [17.4K]

Answer:

b.  =8.5+1.96*3/SQRT(45), and =8.5-1.96*3/SQRT(45)

Step-by-step explanation:

Sample size (n) = 45

Sample mean (M) = 8.5 minutes

Variance (V) = 9 minutes

Z-score for a 95% confidence interval (z) = 1.96

A confidence interval is defined by the following expression:

M\pm z\sqrt{\frac{V}{n} }

Applying the given data:

8.5\pm 1.96\sqrt{\frac{9}{45} }\\8.5\pm 1.96\frac{3}{\sqrt 45}

Writing in Excel statements, the limits of the interval would be

=8.5+1.96*3/SQRT(45), and =8.5-1.96*3/SQRT(45)

Therefore, the answer is alternative b.
