Strong Covid-19 antibodies typically appear about 2 to 4 weeks after complete vaccination. A researcher took a random sample of 15 Covid-19 patients and, for each of these, determined the number of days after complete vaccination that antibodiesappeared. The following are the number of days for each of the patients in our sample:22, 18, 17, 4, 30, 22, 21, 17, 19, 14, 22, 26, 14, 18, 29It is reasonable to treat these measurements as coming from a normal distribution with unknown mean u and unknown standard deviation oCalculate the sample mean of this data.Calculate the sample variance of this data.Use the R, IQR( ) function to find the interquartile range of this data.

Researchers were curious to see if stress affected beta-endorphins. They took beta-endorphin levels for 19 patients 12 hours before surgery (lower stress) and again 10 minutes before surgery (higher stress). Given: SDd-bar = 13.52, SDx1 = 4.40
A study was conducted to determine if lung cancer altered levels of surfactant in the alveoli of the lung. Seven healthy subjects in the study yielded the following data on surfactant levels: 18, 12, 15, 15, 16, 9, 17. Seven lung cancer patients yielded the following results: 16, 8, 7, 15, 11, 12, 9. Do these data indicate a difference in the surfactant level with cancer? Let α = 0.05. Give the p-value.
Do lizards play a role in spreading plant seeds? Some research carried out in a country would suggest so. The researchers collected 400 seeds of this particular type of fig, 100 of which were from each treatment: lizard dung, bird dung, rock hyrax dung, and uneaten figs. They planted these seeds in batches of 5, and for each group of 5 they recorded how many of the seeds germinated. This resulted in 20 observations for each treatment. The treatment means and standard deviations are given in the accompanying table. Treatment n Uneaten figs 20 2.80 0.30 Lizard dung 20 2.75 0.37 Bird dung 20 2.10 0.35 Hyrax dung 20 1.85 0.26 n USE SALT (a) Construct the appropriate ANOVA table, and test the hypothesis that there is no difference between the means for the number of seeds germinating for the four treatments.

A random selection of volunteers at a research institute has been exposed to a weak flu virus. After the volunteers began to have flu symptoms, 20 of them were given multivitamin tablets daily that contained 1 gram of vitamin C and 3 grams of various other vitamins and minerals. The remaining 20 volunteers were given tablets containing 4 grams of vitamin C only. For each individual, the length of time taken to recover from the flu was recorded. At the end of the experiment the following data were obtained.

Capsaicin content in red habanero chilli (Capsicum chinense Jacq.) is affected by the drying process. An experiment was conducted to determine the effect of using different drying temperatures (60 °C, 70 °C, and 80 °C) using an oven. Samples of red habanero chilli were procured. Upon checking, there were varying sizes of chilli and thus the experimenter grouped the samples according to size. Drying temperatures were then randomly assigned within each 8 hours. The capsaicin content was measured for each sample. The partial analysis of variance table is shown below: group for Source of Variation Fc p-value Size 2.1654 0.1560 Temperature 8.6013 0.0034 What is the maximum number of orthogonal contrasts that may be constructed for the post- hoc analysis of the effect of temperature?

A random selection of volunteers at a research institute have been exposed to a typical cold virus. After they started to have cold symptoms, 15 of them were given multivitamin tablets formulated to fight cold symptoms. The remaining 15 volunteers were given placebo tablets. For each individual, the length of time taken to recover from the cold is recorded. At the end of the experiment the following data are obtained.

A researcher conducts a between-subjects study to determine whether low levels of the neurochemical serotonin leads to an increase in aggression. One sample of rats serves as a control group and receives a placebo that does not affect normal levels of serotonin. A second sample of rats receives a drug that lowers brain levels of serotonin. Using an alpha level of a = .05, the researcher then tests the animals by recording the number of aggressive responses each of the rats display. The data are as follows: a.) Step 1: State the Hypotheses Ho: H₁: Control n = 10 M = 14 SS=180.5 b.) Step 2: Determine the critical region and draw it on the distribution above: df = > *critical SM₁-M₂ Low Serotonin n = 15 M = 19 SS = 130.0 c.) Step 3: Calculate the test statistic using the provided sample data: tobs d.) Step 4: Make a decision. Circle one: Reject Null (Ho) or Fail to Reject Null (Ho) e.) State your conclusions about the research scenario in sentence form: d= f.) What is the estimated effect…
