Extracted text: Direction: on a short bond paper, solve the following problems. Show your complete solution. I. INDEPENDENT SAMPLE T-TEST Problem 1: A pilot study was conducted to examine this hypothesis. Ten older adults (over the age of 70) and ten younger adults (between 20 and 30) were given a life satisfaction test (known to have high reliability and validity). Scores on the measuring range from 0 to 60 with high scores indicative of high life satisfaction; low scores indicative of low life satisfaction. Calculate if there is a significant difference between older and younger adults on perceived life satisfaction. Use alpha at 0.05. (Data as follows) (X2)? Younger Adults (Х) 34 No Older Adults (X1)?
