Solve exponential equations: 6^x+3=8
Note: The x+3 is actually the exponent, it is not 6 to the xth power plus 3 equals 8. It is 6 to the x+3 th power equals 8

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.
