Jen thinks a certain potato chip maker is putting fewer chips in their regular bags of chips. From a random sample of 12 bags of potato chips she calculated a P value of 0.143 for the sample. (a) At a 5% level of significance, is there evidence that Jen is correct? (Type: Yes or No): (b) At a 10% level of significance, is there evidence that she is correct? (Type: Yes or No): (c) In a statistical test of hypotheses, we say that the data are statistically significant at level αα if A. the P - value is less than αα. B. the P - value is larger than αα. C. αα is small. D. α=0.05α=0.05.

A random sample of n1 = 299 voters registered in the state of California showed that 146 voted in the last general election. A random sample of n2 = 211 registered voters in the state of Colorado showed that 120 voted in the most recent general election. Do these data indicate that the population proportion of voter turnout in Colorado is higher than that in California? Use a 5% level of significance. I need help with the wrong ones. level of Significance: .05 | H0: p1 = p2; H1: p1 < p2 |
Would you favor spending more federal tax money on the arts? Of a random sample of n1 = 204 women, r1 = 70 responded yes. Another random sample of n2 = 178 men showed that r2 = 48 responded yes.

In a survey, 37% of the respondents stated that they talk to their pets on the telephone. A veterinarian believed this result to be too high, so he randomly selected 200 pet owners and discovered that 73 of them spoke to their pet on the telephone. Does the veterinarian have a right to be skeptical? Use the a = 0.1 level of significance. Because npo (1- Po) 10, the sample size is 5% of the population size, and the sample the requirements for testing the hypothesis satisfied. (Round to one decimal place as needed.)

Males and females were asked what they would do if they received a $100 bill in the mail that was addressed to their neighbor, but had been incorrectly delivered to them. Of the 70 males sampled, 55 said yes they would return it to their neighbor. Of the 130 females sampled, 120 said yes. The overall question is: Is this sufficient evidence to say that the two true proportions are different? Assume that the p-value turns out to be .027 (again not the correct p-value for this situation but use it to answer this question). What is your decision on this hypothesis test using a 5% level of significance? O Fail to reject the null hypothesis Reject the null hypothesis
Generally speaking, would you say that most people can be trusted? A random sample of n. 258 people in Chicago ages 18-25 showed that r₁-40 said yes. Another random sample of n₂ = 287 people in Chicago ages 35-45 showed that r₂- 69 said yes. Does this indicate that the population proportion of trusting people in Chicago is higher for the older group? Use a = 0.05. LAUSE SALT (a) What is the level of significance?

The manufacturer of a popular soft drink claims that cans of this drink contain 12 ounces. A consumer group is suspicious of this claim and believes the amount in each can is less than 12 ounces. A random sample of 18 cans is selected and the amount in each can is measured. The results are as follows: 11.9 11.9 12.0 11.9 12.0 11.7 11.6 11.5 11.6 12.0 11.8 11.7 12.2 11.5 12.1 11.8 12.1 11.8 Calculate the sample standard deviation s.
