When members of a philanthropic organization send out a fundraising letter, they get a return from about 5% of the people ontheir mailing list. They simulated 1000 mailings for samples of size n with success rate p=0.05. The sample statistics fromeach simulation are shown in the table.

A developmental psychologist is interested in studying how long babies gaze at a photograph of a human face. To test this question, she shows a picture to a sample of six babies and records the length of their gaze in seconds. The data are as follows: 12, 17, 18, 20, 20, 29. Calculate the mean, median, mode, range, variance and standard deviation for the sample.
Find the best point estimate for the ratio of the population variances given the following sample statistics. Round your answer to four decimal places. n1=18n1=18, n2=28n2=28, s12=75.455s12=75.455, s22=55.482s22=55.482 Copy Data

Can you guys help me on this? Thank you!
Choose the appropriate statistical test. When computing, be sure to round each answer as indicated. A dentist wonders if depression affects ratings of tooth pain. In the general population, using a scale of 1-10 with higher values indicating more pain, the average pain rating for patients with toothaches is 6.8. A sample of 30 patients that show high levels of depression have an average pain rating of 7.1 (variance 0.8). What should the dentist determine? 1. Calculate the estimated standard error. (round to 3 decimals). [st.error] 2. What is thet-obtained? (round to 3 decimals). 3. What is the t-cv? (exact value) 4. What is your conclusion? Only type "Reject" or Retain"
when computing descriptive statistics, we are interested only both describing our data and also in presenting the means and standard deviations of all dependent variables. True or false When writing your participant section, you include all measures of central tendency (mean, median, mode) and all measures of variablility (variance, range, standard deviation). True or false
