Questions 1, 2, & 3  Thanks! 1. It seems that 14% of engaged women buy a wedding dress at least one size smaller than their current size. Why? Cornell researchers reported an alarming tendency for engaged women to attempt to lose sometimes unhealthy amounts of weight prior to their wedding day (Neighbors & Sobal, 2008). The researchers found that engaged women weighted, on average 152.1 lbs. The average ideal weight reported by 227 women was 136.0. The researchers surveyed a group of students and alum about their weight on the date they bought their wedding dress and again asked them about their weight on the day of their wedding. Did women lost weight for their wedding day? The type of sample in this study is dependent.   True or False?    2. A sample of n = 4 scores has SS = 60. What is the variance for this sample?   3. What is the estimated standard error for a sample of n = 9 scores with SS = 72 in a 1 sample t-test?
