A rope manufacturer wants to test their manufacturing process. Their want their rope to hold at least 500 Ibs. They collect a sample of 85 short pieces of rope and subject each to a pulling force until the rope breaks. The sample mean is X= 495.7" · and sample variance s = 568.4" You are to test the hypothesis Ho:H=500. Calculate the test statistic.
Department secretary has found the average number of complaints per week over the past few years is 1.4. However after a change in major requirements, the complaints over last 8 weeks averaged M = 3.0, with SS = 16. Has there been a significant increase in the number of student complaints over the past 8 weeks? What kind of t-test?______________ Test using alpha = .05 and write an APA style conclusion. 1) H0: H1: 2) Critical value: one or two-tailed? df= __ alpha = .05 __________ 3) Calculations: SS given so start w/ variance s2 SM t = M –µ SM 4) Is there a difference? Reject the Null? Write a sentence with APA stats.

You want to obtain a sample to estimate a population proportion. Based on previous evidence, you believe the population proportion is approximately p*=24%. You would like to be 95% confident that you estimate is within 0.5% of the true population proportion. How large of a sample size is required?n = Do not round mid-calculation. However, use a critical value accurate to three decimal places.

You want to obtain a sample to estimate a population proportion. Based on previous evidence, you believe the population proportion is approximately p∗=28%. You would like to be 99.9% confident that your esimate is within 1% of the true population proportion. How large of a sample size is required?n = Do not round mid-calculation. However, use a critical value accurate to three decimal places.
The drug Tamiflu (oseltamivir phosphate) is used to attack the influenza virus to reduce symptoms for patients. The manufacturer label states that 6% of patients will develop nausea as a side effect. Patients report that nausea occurs at a higher rate than the label indicates. In clinical trials, among 724 patients treated with Tamiflu, 72 experienced nausea as a side effect. Using an α=0.05 level of significance, complete the following steps to determine whether the rate of developing nausea is higher than the manufacturer’s label. (NOTE: All areas are reported to four decimal places; all z-scores are reported to two decimal places except the two special cases listed at the bottom of the table.) Insert the following values from the question: p = % = q = x = n = p̂ = α = Set up the hypothesis statements (no spaces between characters): H0: H1: Based on the hypothesis statements, will you use α or (1 - α) to solve for zcrit? What is the value of zcrit? Use the…
A random sample of 1111 fields of corn has a mean yield of 48.9 bushels per acre and a standard deviation of 4.23 bushels per acre. Determine the 95% confidence interval for the true mean yield. Assume the population is approximately normal. 1. Find the critical value that should be used in constructing the confidence interval. Round your answer to three decimal places. 2. Construct the 95% confidence interval. Round your answer to one decimal place.
