DO IDEAS Homework Help - Q&A from Onl X X C imathas.humber.ca/assess2/?cid=493&laid=14658#/skip/1 I M HUMBER COLLEGE OO STAT1112 A real estate agent Anna Mazowetski was asked to analyze the one-bedroom condo 59mins X prices in the GTA. She took a random sample of 13 condos in Islington and another random sample of 8 condos in Junction. The sample means (in $ thousands) are x1 = 486 for Islington and 2 = 450 for Junction. Historically, the population standard deviations (in $ thousands) are o1 = 63 for Islington and o2 = 24 for Junction. Could Anna Mazowetski claim at a 3% level of significance that the average price in Islington is higher than the average price in Junction?
