Extracted text: 3. Researchers would like to know, for women diagnosed with breast cancer in only one breast, is there a relationship between type of breast cancer a women is diagnosed with and whether they choose to have a single or double mastectomy. To answer, a random sample of 610 women diagnosed with breast cancer in only one breast was obtained. Of those diagnosed with Intraductal Carcinoma, 70 chose to have a single mastectomy while 45 chose to have a double mastectomy. Of the women diagnosed with Invasive Ductal Carcinoma, 120 chose to have a single mastectomy while 90 chose to have a double mastectomy. For the women diagnosed with Invasive Lobular Carcinoma, 75 opted to have a single mastectomy while 85 had a double mastectomy performed. For women diagnosed with Triple-Negative breast cancer, 40 chose to have a single mastectomy while 85 decided to have a double mastectomy. At the 5% significance level, what conclusion can be reached?
