The histogram below is from a simulation of the difference between two populationproportions. The mean and the standard error are calculated using the population proportionvalues and the sample size values.Frequencies of difference in proportions-0.30-0.20-0.100.00 0.05difference in proportionsWhich of the following is the best estimate of the standard error?000sz0000LFrequency

Nikki wishes to test the hypothesis that bird feeders can affect the mean mass of birds in the area surrounding the feeder. She weighs several of the hummingbirds near several feeders. She obtains 4.2, 3.9, 3.6, 3.5, 3.9, 3.8, 3.8, 4.1, 3.9, 3.8, 3.2, and 3.4 as masses in grams for the birds. The student's hypotheses are Ho: µ = 3.65 g and H: µ> 3.65 g. Use technology to calculate the P-value, then determine whether the data provide sufficient evidence to conclude that the mean mass of the birds in the area surrounding the feeder is greater than the mean mass of the general population. Test at the 5% significance level and assume that the population standard deviation is 0.35 g. Also, assess the strength of the evidence against Ho- O A. P= 0.255; since P> 0.05, reject the null hypothesis. The data do provide sufficient evidence to conclude that the mean mass of the birds in the area is greater than the mean mass of the general population. The evidence against the null hypothesis is…

Cuckoo birds are in the habit of laying their eggs in other birds' nest. The other birds adopt and hatch the eggs. The lengths (in cm) of cuckoo birds' eggs in the other species nests were measured and are in the table. Do the data show that the mean length of cuckoo bird's eggs is not all the same when put into different nests? Test at the 10% level.

An insurance company samples claim forms for errors created by its employees as well as the amount of time it takes to process a claim. UCL (a) When the process is in control, the proportion of claims with an error is 0.035. A p chart has LCL = 0 and UCL = 0.072. Plot the following seven sample results: 0.035, 0.062, 0.055, 0.049, 0.058, 0.066, and 0.055. 0.08 0.06 0.04 0.02 0.00 Sample Proportion 12 LCL 34567 Sample Number 0.08 0.06 0.04 0.02 0.00 Sample Proportion UCL LCL 1 2 3 4 5 6 7 Sample Number Sample Proportion 0.08- 0.06 0.04 0.02 0.00 UCL LCL 1 2 34567 Sample Number 0.08 0.06 0.04 0.02 0.00 Sample Proportion UCL LCL 1 2 3 4 5 6 7 Sample Number Comment on whether there might be concern about the quality of the process.

The process should be checked. The data points indicate a strong trend over time. The…
Compare and contrast the two samples measures of central tendency. Compare and contrast the two samples of variation. What would you expect to the be the average height of all of the players? What would you expect the range of the height to be of all of the players?
For each case below, state what type of statistical test you would use to analyze each dataset. Explain your answer! Hemoglobin is a protein responsible for carrying oxygen throughout your blood stream. Blood hemoglobin levels in humans average at about 14.5g/dL. We are interested in whether a sample of 20 iron deficient individuals have lower blood hemoglobin levels compared to the general population. The average hemoglobin level for our sample is 10.9g/dL, with an estimated population standard deviation of 1.92g/dL. A researcher is looking at whether the time it takes for rats to relearn how to run a maze decreases after they’ve been exposed to the maze more than once. Using 15 rats, he measures how quickly they are able to successfully run a maze at two different times points: once when they are first exposed to the maze, and again after they’ve run the maze three times. A social psychologist is curious about whether social rejection increases aggression in narcissists. He…

A professor believes that his math students have different IQ than the average college students. He collected the IQ scores of 30 students in his class. Then, he compared it to the average IQ score of college students. Provided below is the data that the professor gathered.Sample:Mean: 103 Std. Dev: 7 N: 30 Population: Mean: 100 Std. Dev: 5 A). What is the type of test you will use? (z-test, single-sample t-test, paired-samples t-test, or independent samples t-test) and why (what information provided in the problem) B). What are the hypotheses (Be Specific)
