he nutrition label on a bag of potato chips says that a one ounce (28 gram) serving of potato chips has 130 calories. A random sample of 35 bags yielded a sample mean of 138 calories vith a standard deviation of 17 calories. Is there evidence that the nutrition label does not provide an accurate measure of calories in the bags of potato chips? You may assume that the umber of calories per serving is normally distributed with standard deviation equal to the standard deviation of the sample. a) State the null and alternative hypotheses. Ο H : μ- 130; H: μ + 130 O Ho: H = 130; H: µ > 130 Ο H: μ< 130; H,: μ - 130 Ο H0: μ > 130; H,: μ= 130 Ο H : μ- 130; H.: μ < 130 b) Give the z-score to two decimal places and the P-value to 4 decimal places.

Question
The nutrition label on a bag of potato chips says that a one ounce (28 gram) serving of potato chips has 130 calories. A random sample of 35 bags yielded a sample mean of 138 calories
with a standard deviation of 17 calories. Is there evidence that the nutrition label does not provide an accurate measure of calories in the bags of potato chips? You may assume that the
number of calories per serving is normally distributed with standard deviation equal to the standard deviation of the sample.
a) State the null and alternative hypotheses.
O Ho: H = 130; H,: µ # 130
O Ho: µ = 130; H,: µ > 130
O Ho: H < 130; H¸: µ = 130
Ho: µ > 130; H,: µ = 130
ΟH0: μ 130; Η.: μ< 130
b) Give the z-score to two decimal places and the P-value to 4 decimal places.
