In a survey, 33% of the respondents stated that they talk to their pets on the telephone. A veterinarian believed this result to be too high, so she randomly selected 210 pet owners and discovered that 66 of them spoke to their pet on the telephone. Does the veterinarian have a right to be skeptical? Use the a=0.01 level of significance. Because npo (1-Po) = 10, the sample size is (Round to one decimal place as needed.) What are the null and alternative hypotheses? Ho versus H₁ (Type integers or decimals. Do not round.) Find the test statistic, Zo Zo= (Round to two decimal places as needed.) Find the P-value. 5% of the population size, and the sample the requirements for testing the hypothesis P-value= (Round to three decimal places as needed.) Does the veterinarian have a right to be skeptical? OA. The veterinarian has a right to be skeptical. There is sufficient evidence to conclude that the true proportion of pet owners who talk to their pets on the telephone is less than 33%. OB.…
In a survey, 36% 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 240 pet owners and discovered that 85 of them spoke to their pet on the telephone. Does the veterinarian have a right to be skeptical? Use the x = 0.1 level of significance. Because npo (1-P) = 55.3 > 10, the sample size is (Round to one decimal place as needed.) What are the null and alternative hypotheses? Ho: versus H₁: (Type integers or decimals. Do not round.) less than 5% of the population size, and the sample is given to be random, the requirements for testing the hypothesis are satisfied.
Suppose that the sample average is 44.4 while the null hypothesis is that the population mean is 44. If the standard error is 1 then what is the t test statistic? (Answer to 4 decimal places if necessary).
Make a hypothesis test on two population means orproportions for variables X and Y are satisfied. If not, deliberate the assumptions youneed to make about the two populations to satisfy the condition. Explain how to choosea distribution and justify the assumption made about the unknown populationvariances.Perform a hypothesis test of two-sample mean or proportion comparison for variablesX and Y using the p-value approach at a 5% significance level. Then, interpret yourresult.Give an example for each of the Type I and Type II errors.
A manufacturer of capacitors claims the breakdown voltage has a mean value of at least 1 00 V. A test of nine capacitors yielded breakdown voltages of 97, 104, 95, 98, 106, 92, 110, 103, and 93 V.a) Find the sample mean.b) Find the sample variance using an unbiased estimate.c) Is the manufacturer's claim valid if a confidence level of 95% is employed?
An assembly line will be shut down for maintenance if the defect rate exceeds 2.3%. Suppose you adopt a 5% significance level and take a random sample 200 items off the assembly line and compute the proportion that are defective. For what values of the sample proportion will the assembly line be shut down?
Define the related-repeated (pre/post) two-sample t-test and the related-matched two-sample t-test.
Perform a hypothesis test to determine whether there is a difference in the mean attendance of teams between the two groups created in Part F. Use a 0.05 level of significance in your testing procedures. Hint: When calculating your pooled sample variance and your test statistic, assume the Top 10 data is sample 1 and the Bottom 10 data is sample 2. Decision Rule -t < or t > = REJECT H0 Value of Pooled Sample Variances Value of test statistic Decision: enter Reject or Do Not Reject Is there a difference in the mean attendance between the two groups assuming a 0.05 level of significance? Enter Yes or No. Another variable that can impact attendance is the team's win-loss record. Teams that are winning more games are thought to have increased attendance as fans prefer to see their home team "win" rather than "lose" (although for some teams such as the Chicago Cubs, this is not always an established relationship!). Create 2 samples…
4) Consider a confidence level of 90%. If n=68 and ?̂ = 0.42 Calculate the margin of error. 5) Consider a confidence level of 87%, let ? = 0.02 and ?̂ = 0.42. Find the sample size ?.
N1=26 n2=13 Mean1=48 mean2=45 Standard deviation1=9,2 Standard deviation2=4,1 b) Construct a 95% confidence interval to test whether the two sample means differs. Interpret your answers. c) State the assumptions used
b) Based on sample size of N=31 and sample statistics x = 50.6077 unit, s², = 1.9874 unit? determine the whole population statistics at 90% confidence level, also estimate the population mean from the sample data at 95% confidence level.
