Ciara solved the exponential equation 3x+1 = 15 and her work is shown below. what is the first step she did incorrectly?

step 1: log 3x+1 = log15
step 2: (x + 1)log 3 = log15
step 3: log3 = log 15 over x plus 1
step 4: 0.477121 = 1.176091 over x plus 1
step 5: 0.477121(x + 1) = 1.176091
step 6: x + 1 = 1.176091 over 0.477121
step 7: x + 1 = 2.464975
step 8: x = 1.464975

According to a study conducted in 2015, 18% of shoppers said that they prefer to buy generic instead of name-brand products. suppose that in a recent sample of 1500 shoppers, 315 stated that they prefer to buy generic instead of name-brand products. at a 5% significance level, can you conclude that the proportion of all shoppers who currently prefer to buy generic instead of name-brand products is higher than .18? use both the p-value and the critical-value approaches.
