Calvin thinks a certain potato chip maker is putting fewer chips in their regular bags of chips. From a random sample of 23 bags of potato chips he calculated a P value of 0.061 for the sample.(a) At a 5% level of significance, is there evidence that Calvin is correct? (Type: Yes or No):(b) At a 10% level of significance, is there evidence that he is correct? (Type: Yes or No):(c) In a statistical test of hypotheses, we say that the data are statistically significant at level a ifO A. the P-value is less than aO B. the P-value is larger than aOC. a = 0.05.D. a is small.

The p-value is 0.061 Sample size, n=23

The records of a light bulb manufacturer show that, when the manufacturing machinery is working correctly, the defect rate (due to imperfections in the material used) is 1%. The manufacturer's control department periodically tests samples of the bulbs, and when 1.25% or more are defective, they call repair technicians for service. The control department is going to take a random sample of 4400 light bulbs. Let p be the proportion of defective light bulbs in the sample assuming the machinery is working correctly. A) find the mean of p b)find the standard deviation of p c)Compute an approximation for P≥p0.0125, which is the probability that, assuming the machinery is working correctly, the repair technicians will be called. Round your answer to four decimal places.

The control department is going to take a random sample of 4400 light bulbs. Let p be the proportion of defective light bulbs in the sample assuming the machinery is working correctly. Answer the following. (If necessary, consult a list of formulas.) (a) Find the mean of p. (b) Find the standard deviation of p. (c) Compute an approximation for P(P ≥ 0.0125), which is the probability that, assuming the machinery is working correctly, the repair technicians will be called. Round your answer to four decimal places.
A newspaper conducted a statewide survey concerning a proposal to raise taxes in order to prevent budget cuts to education. The newspaper took a random sample (assume it is an SRS) of 400 registered voters and found that 160 would vote to raise taxes. Let p represent the proportion of registered voters in the state that would vote to raise taxes. (Round your answers to 4 decimal places, if needed.) (a) The standard error for the sample proportion is (b) The margin of error for an 88% confidence interval for p is Check
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.

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?

A study is made of residents in Phoenix and its suburbs concerning the proportion of residents who subscribe to Sporting News. A random sample of n, = 86 urban residents showed that r, = 14 subscribed, and a random sample of n, = 97 suburban residents showed that r = 20 subscribed. Does this indicate that a higher proportion of suburban residents subscribe to Sporting News? Use a 5% level of significance. What are we testing in this problem?

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.
