Matrices

‘Matrices’ is the plural form of the word matrix, and it is basically a spreadsheet in the form of a box. In mathematics, various functions can be carried out with matrices. Generally, a matrix comes in the shape of a square or rectangle. The elements are distributed horizontally in the form of rows, and vertically in the form of columns.

Question

Look at the picture and please provide full explanation answer

10. When appropriate, refer to the StatCrunch analysis
you believe is correct in this problem. Ramp metering is
a traffic engineering idea that requires cars entering a
freeway to stop for a certain period of time before joining
the traffic flow. The theory is that ramp metering controls
the number of cars accessing the freeway, resulting in a freer
flow of cars, which ultimately results in faster travel times.
To test whether ramp metering is effective in increasing
travelling speeds, engineers in Minneapolis, Minnesota,
conducted an experiment in which a section of freeway had
ramp meters installed on the on-ramps. A random sample of
15 cars on the highway for a Monday at 6 P.M. with the
ramp meters on and a second random sample of 15 cars on a
different Monday at 6 P.M. with the meters off had their
speeds measured. Is there evidence of a significant
improvement with the ramp metering in place? Use a 10%
significance level.
