The British Department of Transportation studied to see if people avoid driving on Friday the 13th. They did a traffic count on
Maurinko [17]

Answer: The mean difference is between 799586.3 and 803257.9.

Step-by-step explanation: To estimate the mean difference for confidence interval:

Find the statistic sample:

  • d = value of 6th - value of 13th;
  • Sample mean of difference: mean = ∑d / n
  • Sample standard deviation: s = ∑(d - mean)² / n - 1;

For the traffic count, mean = 1835.8 and s = 1382607.3

The confidence interval is 90%, so:

α = \frac{1-0.9}{2}

α = 0.05

The degrees of dreedom are:

df = n - 1

df = 10 - 1

df = 9

Using a t-ditribution table, the t-score for α = 0.05 and df = 9 is: t = 1.833.

Error will be:

E = t.\frac{s}{\sqrt{n} }

E = 1.833.(\frac{1382607.3}{\sqrt{10} })

E = 801422.1

The interval is: mean - E < μ < E + mean

1835.8 - 801422.1 < μ < 1835.8+801422.1

-799586.3 < μ < 803257.9

The estimate mean difference in trafic count between 6th and 13th using 90% level of confidence is between 799586.3 and 803257.9.
