Step 1
In this case, we are testing whether the variance of carbohydrates in fast-food entrees differs from 100. Therefore, our hypotheses are: - H0: σ^2 = 100 (The population variance equals 100) - Ha: σ^2 ≠ 100 (The population variance does not equal 100) This is a Show more…

Assume that the variables are normally or approximately normally distributed. Use the traditional method of hypothesis testing unless otherwise specified. The number of carbohydrates found in a random sample of fast-food entrees is listed. Is there sufficient evidence to conclude that the variance differs from $100 ?$ Use the 0.05 level of significance. $\begin{array}{lllll}53 & 46 & 39 & 39 & 30 \\ 47 & 38 & 73 & 43 & 41\end{array}$
Hypothesis Testing
????2 Test for a Variance or Standard Deviation
For Exercises 5 through $20,$ assume that the variables are normally or approximately normally distributed. Use the traditional method of hypothesis testing unless otherwise specified. Carbohydrates in Fast Foods The number of carbohydrates found in a random sample of fast-food entrees is listed. Is there sufficient evidence to conclude that the variance differs from $100 ?$ Use the 0.05 level of significance. $$ \begin{array}{lllll}{53} & {46} & {39} & {39} & {30} \\ {47} & {38} & {73} & {43} & {41}\end{array} $$
