A program claims to teach students how to type 60 words per minute. After the program, 30 randomly selected students were tested. They had an average typing speed of 58.8 words per minute (wpm) with a standard deviation of 6.7 wpm. A researcher performed a test of hypothesis to determine if this provide sufficient evidence to conclude that program produces students with a mean typing speed less than 60 wpm, producing a p-value of 0.167. Which is a correct statement that belongs in the conclusion? O Since the p-value is greater than 0.05, we reject Ho. O Since the p-value is less than 0.05, we reject Ho. Since the p-value is greater than 0.05, we accept Ho. Since the p-value is greater than 0.05, we fail to reject Ho.
