In October 2003 the mean sale price of a single family home in Santa Clara County was $683,008.  We are interested in determining whether the prices in Cupertino were greater than the county average. We randomly survey 10 Cupertino single family home sale prices in the same time period and find a mean of $703,329 and a standard deviation of $21,403. At a 5% level of significance, the correct decision is: Group of answer choices   Reject Ho   Do not reject Ho
