WORK:

The National Highway Traffic Safety Administration reported the percentage of traffic accidents occurring each day of the week. Assume that a sample of 420 accidents provided the following data.

(a)

Conduct a hypothesis test to determine if the proportion of traffic accidents is the same for each day of the week. Use a 0.05 level of significance.

State the null and alternative hypotheses.

H₀: p_Sun = p_Mon = p_Tue = p_Wed = p_Thu = p_Fri = p_Sat =

H_a: Not all proportions are equal.H₀: Not all proportions are equal.
H_a: p_Sun ≠ p_Mon ≠ p_Tue ≠ p_Wed ≠ p_Thu ≠ p_Fri ≠ p_Sat ≠

    H₀: Not all proportions are equal.
H_a: p_Sun = p_Mon = p_Tue = p_Wed = p_Thu = p_Fri = p_Sat =

H₀: p_Sun ≠ p_Mon ≠ p_Tue ≠ p_Wed ≠ p_Thu ≠ p_Fri ≠ p_Sat ≠

H_a: All proportions are equal.

Find the value of the test statistic. (Round your answer to three decimal places.)

Find the p-value. (Round your answer to four decimal places.)

p-value =

State your conclusion.

Reject H₀. We conclude that the proportion of traffic accidents is not the same for each day of the week.Do not reject H₀. We conclude that the proportion of traffic accidents is the same for each day of the week.     Do not reject H₀.

I can understand how the percentage of dark matter compared to ordinary matter is calculated, because the amount of dark matter has a clear gravitational effect on the ordinary matter in a Galaxy.

However, calculating the percentage of dark energy in the universe seems less obvious. Is it something to do with the rate of expansion of space-time?

Please explain in lay-mans terms, I've never learnt any undergraduate level cosmology.
