using the sequential step of hypothesis testing A poultry raiser harvests an average of 300 eggs perday. He has recently experimented with the differenttypes of poultry feeds. As a result, he noticed somefluctuation in the number of eggs laid by the chickens,which is neither clearly higher nor lower than previousweeks. He decides to find out whether there might bea significant change in the number of eggs laid by thechickens. He records his harvest of eggs for 20 days. Hefinds that the average per day is 290 eggs with astandard deviation of 15. At 5% level of significance,what did the poultry raiser find out?

It is given that Sample size n = 20 Sample mean M = 290 Sample SD s = 15 Level of significance =…

Only 25% of registered voters voted in the last election. Will voter participation higher for the upcoming election? Of the 600 randomly selected registered voters surveyed, 192 of them will vote in the upcoming election. Perform a hypothesis test and use a = .05 level of significance? Step (1) Determine the null and alternative hypotheses. Ho: p= 0.25 Ho: p0.25 Step (2) Determine the test statistic and p-value.

st 3 4 25 26 27 28 on 29 K Test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, and then state the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Among 2073 passenger cars in a particular region, 222 had only rear license plates. Among 339 commercial trucks, 51 had only rear license plates. A reasonable hypothesis is that commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passenger cars. Use a 0.10 significance level to test that hypothesis. a. Test the claim using a hypothesis test. b. Test the claim by constructing an appropriate confidence interval. a. Identify the null and alternative hypotheses for this test. Let population 1 correspond to the passenger cars and population 2 correspond to the commercial trucks. Let a success be a vehicle that only has a rear license plate. O A. Ho: P₁ = P2 H₁: P₁ P2 OB. Ho: P₁ P2 H₁: P₁ P2 OC.…
Inferential Statistics Are the M&M’s weights accurate? According to the package, each small bag of peanut M&M’s should weigh 49.3 grams. To determine if the bag weights are on target, use the weight of the bags of M&M’s and conduct a hypothesis test to see if the company’s claim is true. Using α = .05 and the five-step process, be sure to include your hypotheses and work. Calculate the corresponding confidence interval for the mean of the weights. Does your results and decision in this problem match the decision you made in Problem 5? Is the average number of orange M&M’s in a bag different from the average number of brown M&M’s? Conduct a hypothesis test at the α = .05 level to answer that question. The following data set includes information from 30 bags of M&M’s. For each bag, the count for each color is provided as well as the bag’s weight prior to it being open. Bag # Red Green Blue Orange Yellow Brown Weight 1…

The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject Ho when the level of significance is (a) a = 0.01, (b) a= 0.05, and (c) a= 0.10 P= 0.1129 (a) Do you reject or fail to reject H, at the 0.01 level of significance? ur O A. Fail to reject H, because the P-value, 0.1129, is greater than a= 0.01. O B. Reject H, because the P-value, 0.1129 , is greater than a= 0.01. O C. Reject H, because the P-value, 0.1129, is less than a= 0.01. O D. Fail to reject Ho because the P-value, 0.1129, is less than a = 0.01. rai
