An analyst for a firm claims that their market-share has increased. In the past, about 35% of households used their product. To test the claim, they set up the following (p is the population proportion of households that use their product): HO: p <= 0.35 H1: p > 0.35 To carry out the test at a significance level of 10%, the analyst took a random sample of households (sample size = 80), and found the sample proportion of households that used their product, and it was 40 out of 80. Compute the appropriate Z-stat. (provide two decimal places)
