Answer:
There is evidence that the nutrition label does not provide an accurate measure of calories in the bags of potato chips at 5% level of significance.
Step-by-step explanation:
Given that the nutrition label on a bag of potato chips says that a one ounce (28 gram) serving of potato chips has 130 calories and contains ten grams of fat, with three grams of saturated fat.
Sample size of 35 gave mean as 134 with s = sample std dev = 17
(two tailed test)
Mean difference =
Std error of sample mean =
Since only sample std deviation is known, we use t test
df =34
t = mean diff/std error = 1.392
=0.1729
Let us fix significance level as 5%
since p <0.05 we reject null hypothesis
There is evidence that the nutrition label does not provide an accurate measure of calories in the bags of potato chips

Answer:
2,058
Step-by-step explanation:
first term : a_1 = 6
common ratio r = 7
a_n = (a_1) * r ^(n-1)
a_4 = 6 * 7^(4-1)
a_4 = 6 *7^3
a_4 = 6 * 343 = 2,058
