When bonding teeth, orthodontists must maintain a dry field. A new bonding adhesivecalled "Smartbond" has been developed to eliminate the necessity of a dry field. However,there is concern that the new bonding adhesive is not as strong as the current standard, acomposite adhesive (Trends in Biomaterials & Artificial Organs, Jan. 2003).Tests on a sample of 10 extracted teeth bonded with the new adhesive resulted in a meanbreaking strength (after 24 h) of = 5.07 Mpa (megapascal). Orthodontists want to knowif the true mean breaking strength of the new bonding adhesive is less than 5.70 MPa, themean breaking strength of the composite adhesive. Conduct the appropriate analysis forthe orthodontists at level a = 0.01 when:(1) The standard deviation has been estimated to be s = 0.46 MPa;(2) The standard deviation of the population distribution is known to be o = 0.46 MPa.

Known for their grand design and impeccable aesthetic, UQ's lecture theatres are well appreciated by their students. In fact, some lecture theatres even have sound systems with high quality sound opposed to standard sound. However, the high quality sound systems face issues and sometimes do not work faultlessly. In fact, it is known that these high quality sound systems work faultlessly 86% of the time each week. A random sample of 10 lecture theatres with high quality sound is selected and monitored over the week. What is the probability that these lecture theatres work faultlessly more than seven times? (3 decimal places) Note:- Do not provide handwritten solution. Maintain accuracy and quality in your answer. Take care of plagiarism. Answer completely. You will get up vote for sure.
An advertising agency is studying social media campaigns and how they impact website traffic. The advertising agency states the average increase in website traffic after a social media campaign is greater than 20 percent. If we would like to test the advertising agency's claim with a hypothesis test using a significance level of α = 0.015, what is the rejection region? Use the graph below to show the rejection region. First, move the blue dot to choose the appropriate test (left-, right, or two- tailed). Then, slide the shaded region(s) to represent the rejection region. Provide your answer below:
The article "Well-Fed Crickets Bowl Maidens Over"† reported that female field crickets are attracted to males that have high chirp rates and hypothesized that chirp rate is related to nutritional status. The chirp rates for male field crickets were reported to vary around a mean of 60 chirps per second. To investigate whether chirp rate is related to nutritional status, investigators fed male crickets a high-protein diet for 8 days and then measured chirp rate. The mean chirp rate for the crickets on the high-protein diet was reported to be 101 chirps per second. Is this convincing evidence that the mean chirp rate for crickets on a high-protein diet is greater than 60 (which would then imply an advantage in attracting the ladies)? Suppose that the sample size and sample standard deviation are n = 32 and s = 40. You can test the relevant hypotheses to answer this question. A significance level of ? = 0.01 will be used. a) State the null and alternative hypotheses. H0: ? =…

Use a z-table such as https://www.math.arizona.edu/~rsims/ma464/standardnormaltable.pdf or an online calculator such as http://onlinestatbook.com/2/calculators/normal_dist.html to answer the following question: This question again refers to the study on blood pressure which has a normally-distributed set of blood pressures with a mean of 120.1 mmHg and a standard deviation of 15.1 mmHg. If you picked a member of the population at random, would it be more likely that you randomly select someone that: Has a blood pressure between 104 mmHg and 114 mmHg, or Has a blood pressure between 124 mmHg and 134 mmHg? Show any values calculated and explain your reasoning in the space provided below.
