A company claims its 12 week exercise program significantly reduces weight.A random sample of 6 persons was selected and their weight in kg measured before and after the program.

Before 91 84 109 142 94 120

After 86 88 100 121 92 111

At 5% significant level can you conclude that the mean weight loss is greater than zero?Assume the population is normally distributed. How about at 1% significant level?

Let population 1 = Before

Let population 2 = After

Mean of Matched Pair Differences (round to two decimal place)

Standard Deviation of Matched Pair Differences (round to two decimal places)

T test statistic for the Matched Pair Hypothesis (round to two decimal places)

At 5% significance level, do you reject the null hypothesis (insert Y or N)

At 1% significance level, do you reject the null hypothesis (insert Y or N)
