State your null hypothesis (H0) and alternative hypothesis (H1)
State your assumed level of significance (αα)
Calculate mean for sample 1
Calculate mean for sample 2
Calculate grand mean for sample 1 & 2
Calculate SSB (between sample sum of square errors) and the associated degree of freedom
Calculate SSW (within sample sum of square errors) and the associated degree of freedom
Calculate SST (total sample sum of square errors) and the associated degree of freedom (Hint: this validates the accuracy of your calculated SSB and SSW values)
Calculate the F value
State the critical F value (table value based on your assumed level of significance)
Make your conclusion whether or not the speed reduction strategy was effective and state why?
Answer by hand not excel please.

You want to determine the speed limit for a local highway.
Distribution data for the driving speed on a given street is given
below; all speeds have been rounded to the nearest integer. Part a:
What is the average(mean) and standard deviation of this sample of
data? (Hint, you will need to manipulate the data – you cannot use
the average or stdev functions in excel on the data as is.) Part b:
What is the value that 85% of...

The accompanying data show spot speeds collected at a
section of highway located in a residential area. (i) Using the
student’s t test, determine whether there was a
statistically significant difference in the average speeds at the
95% confidence level. (ii) Also report for before and after the
following: mean speed, standard deviation, 85th
percentile speed and percentage of traffic exceeding the posted
speed limit of 30 MPH. (iii) using the data, draw the histogram
