During a 60-minute period, a traffic engineer counted 54 trucks and cars that crossed a bridge. The ratio of trucks to cars that
d1i1m1o1n [39]

Answer:

Step-by-step explanation:

Given the expression for the equation representing the prediction of number of trucks as;

2/7 = t/54-t where t is the number of trucks

To get the number of trucks t, we will have to evaluate the expression and solve for t as shown;

Given 2/7 = t/54-t

Cross multiply

2(54-t) = 7t

Open the parenthesis

2(54)-2t = 7t

108-2t = 7t

7t+2t = 108

9t = 108

Divide both sides by 9

9t/9 = 108/9

t = 21

Hence the engineers should have counted 21trucks

Mark is using a one-sample t-test on the following group:
irga5000 [103]

Based on the one-sample t-test that Mark is using, the two true statements are:

  • c.)The value for the degrees of freedom for Mark's sample population is five.
  • d.)The t-distribution that Mark uses has thicker tails than a standard normal distribution.

<h3>What are the degrees of freedom?</h3><h3 />

The number of subjects in the data given by Mark is 6 subjects.

The degrees of freedom can be found as:

= n - 1

= 6 - 1

= 5

This is a low degrees of freedom and one characteristic of low degrees of freedom is that their tails are shorter and thicker when compared to standard normal distributions.

Options for this question are:

  • a.)The t-distribution that Mark uses has thinner tails than a standard distribution.
  • b.)Mark would use the population standard deviation to calculate a t-distribution.
  • c.)The value for the degrees of freedom for Mark's sample population is five.
  • d.)The t-distribution that Mark uses has thicker tails than a standard normal distribution.
  • e.)The value for the degrees of freedom for Mark's sample population is six.
