For this question, you need to evaluate a claim by considering whether it is supported by a confidence interval. Copy the confidence from Q3 Write down the name of the beach you identified as having the higher sample proportion of plastics from Q1. Write one sentence evaluating a claim that “The proportion of all litter on this beach that is plastic is higher than that of the other beach” by considering whether it is supported by the confidence interval. Construct your answer using the following structure. Copy and paste it into the template and complete your answers accordingly. The confidence interval from Q2/3: The beach with the higher sample proportion from Q1: One sentence evaluation of whether the claim can be made:

The overall research question for this task is “How does the proportion of all litter on beach one that is plastic compare to the proportion of all litter on beach two that is plastic?” The confidence interval is (0.277,0.451) the sample proportion for plastic litter from first beach is 0.386, sample size of first beach is 448 and the the sample proportion for plastic litter from second beach is 0.75，sample size of second beach is 132.........For this question, you need to evaluate a claim by considering whether it is supported by a confidence interval.

Data + People is one of the five learning outcomes of this course. In this week’s task, you used sample surveys of beaches to quantify the proportion of litter that was plastic. Describe how a similar survey-based approach could be used to investigate the proportion of household recycling that is plastic. Write two to three sentences.

A 95% confidence interval for the proportion of sea fans infected on the Las Redes Reef was calculated to be (0.423, 0.615)Based on this confidence interval, which one of the following statements is necessarily TRUE?Group of answer choices51.9% of all sea fans on the Las Redes Reef are infectedIf the study was repeated many times over, and the sample proportion of infected sea fans (p-hat) was recorded each time, then we would expect approximately 95% of the resulting estimates (the p_hat's) to be between (0.423 0.615).51.9% of all sea fans are infected.We don't know exactly what proportion of sea fans on the Las Redes Reef are infected but we know that it is definitely between 0.423 and 0.615.We can be 95% sure that the proportion of sea fans infected on the Las Redes Reef is between 0.423 and 0.615.

CASE STUDYIn air pollution study, Ozon measurement were taken in a large California city at 5.00 PM. The eight readings (in parts per million) were7.9,  11.3,   6.9 ,   12.7,   13.2,  8.8,  9.3 , 10.6Assuming the population sampled is normal. Test the null hypothesis for population mean 9.8.choose all possible options for the caseGroup of answer choicesThe alternative hypothesis should be stated as less then or greater thanIt is a case which need t table to find value of confidence intervalThis is a case of single tail problem as the mean of sample is larger than the mean of populationIt is a case which need Z table to find value of confidence intervalalternative hypothesis statement should be written as greater thanalternative hypothesis statement should be written as greater thanThis is a case of two tail problem
