Robert Anderson is hiding

I asked for his polling information on the Ambulance service, and he has failed to deliver. Questions posted my Kitty. What was the name of the company that performed the scientific telephone phones? What type of sampling technique did they use, was it a stratified sample, cluster sample or systematic sample? Mr. Anderson stated a random sample, without identifying the type; one cannot infer whether sample was representative of the population. Additionally, was a hypothesis test performed for the mean? What was the null and alternative hypothesis? What were the confidence interval, level of significance, sampling distribution and critical values? Did they identify the standard deviation for this scientific poll?
