The American Hospital Administrators Association (AHAA) reports the following information concerning the number of times senior citizens are admitted to a hospital during the Corona Virus outbreak. Forty percent are not admitted; 30 percent were admitted the first week; 20 percent the second week, and the remaining 10 percent were admitted the third week.

A survey of 200 residents of a local Senior Center, a community devoted to active seniors located in a hot bed political location, revealed 70 residents were not admitted during the outbreak, 70 were admitted to a hospital during the first week, 35 were admitted during the second week, and the remaining 25 were admitted during the third week. Your local Health expert is screaming during the news conference that 65% of the residents have been admitted and the city needs to be put on lockdown because this is almost two thirds higher than average!

Can we conclude the local senior center is consistent with the information suggested by the AHAA or is the EXPERT correct in their rhetoric?

Use the .05 significance level?

The null hypothesis and the alternate hypothesis are the following:

H0: There is no difference between local and national experience for hospital admissions.

H1: There is a difference between local and national experience for hospital admissions.

Use the following table to compute Chi Squared and make a decision.
