A restaurant owner Installed a new automated drink machine. The machine Is designed todispense 530 mL of liquid on the medium size setting. The owner suspects that themachine may be dispensing too much In medlum drinks. They decide to take a sample of30 medium drinks to see If the average amount Is significantly greater than 530 mL.What are appropriate hypotheses for their significance test?1. Ho : p 530 mL, H: p> 530 mL(where p Is the proportion of liquid dispensed on this setting)2. Ho : p= 530 mL, H1: p< 530 mL(where p Is the proportion of liquid dispensed on this setting)3. Họ : µ= 530 mL, H : p > 530 mL(where u Is the average amount of liquid dispensed on this setting)4. Ho: μ=530mL , H μ< 530mL(where u Is the average amount of liquld dispensed on this setting)

Given,sample size(n)=30population mean(μ)=530Claim: The average amount is significantly greaterthan…

I didnt mean to select an option on the second portion but I need help solving this.
The manufacturer claims that your new car gets 28 mpg on the highway. You suspect that the mpg is more for your car. The 66 trips on the highway that you took averaged 32 mpg and the standard deviation for these 66 trips was 10.9 mpg. What can be concluded at the αα = 0.05 level of significance? For this study, we should use Select an answer t-test for a population mean z-test for a population proportion Correct The null and alternative hypotheses would be: H0:H0: ? p μ CorrectSelect an answer ≤ = ≥ ≠ Ha:Ha: ? μ p CorrectSelect an answer = < > ≠ The test statistic ? z t Correct = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.) The p-value is ? ≤ > Correct αα Based on this, we should Select an answer accept fail to reject reject Incorrect the null hypothesis. Thus, the final conclusion is that ... The data suggest that the sample mean is not significantly more than 28 at αα = 0.05, so there is…
The claim is that smokers have a mean cotinine level greater than the level of 2.84 ng/mL found for nonsmokers. (Cotinine is used as a biomarker for exposure to nicotine.) The sample size is n=761 and the test statistic is t=55.668. Use technology to find the P-value. Based on the result, what is the final conclusion? Use a significance level of 0.10. State the null and alternative hypotheses. H₁> 2.84 2.84 (Type integers or decimals. Do not round.) The test statistic is (Round to two decimal places as needed.)

The manufacturer claims that your new car gets 24 mpg on the highway. You suspect that the mpg is less for your car. The 44 trips on the highway that you took averaged 22.3 mpg and the standard deviation for these 44 trips was 4.2 mpg. What can be concluded at the αα = 0.05 level of significance? For this study, we should use (t-test for population mean, z-test for population proportion) The null and alternative hypotheses would be: H0: (symbol) (symbol) ____ H1: (symbol) (symbol) ____ The test statistic (?,t,z) = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.) The p-value is (?, less than or equal to, more than) αα Based on this, we should (accept, reject, fail to reject) the null hypothesis. Thus, the final conclusion is that ... The data suggest that the sample mean is not significantly less than 24 at αα = 0.05, so there is statistically insignificant evidence to conclude…

Suppose you want to test the claim that μ = 3.5. Given a sample size of n = 35 and a level of significance of a = 0.10 when should you reject Ho? This represents a The curve. hypothesis represents the claim. Reject Ho if the standardized test statistic is 10 or
A safety administration conducted crash tests of child booster seats for cars. Listed below are results from those tests, with the measurements given in hic (standard head injury condition units). The safety requirement is that the hic measurement should be less than 1000 hic. Use a 0.01 significance level to test the claim that the sample is from a population with a mean less than 1000 hic. Do the results suggest that all of the child booster seats meet the specified requirement? 600 662 1092 545 496 541 what are the hypothesis? identify the test statistics identify the P-value state the final conclusion that addresses the original claims what do the results suggest about the child booster seats meeting the specified requirement?
