An animal shelter recorded the weight of each of the 43 large breed dogs admitted last week. The smallest weight was 20 kg, and the largest was 27kg. The table gives the mean, median, range, and interquartile range (IQR) of the data set. SUMMARY VALUES Mean Median Range IQR 23.5 23.5 7 1
Can you help me with the p-value I answered 0.034 which is incorrect
Suppose IQ scores were obtained for 20 randomly selected sets of siblings. The 20 pairs of measurements yield x = 101.13, y = 103.5, r=0.867, P-value = 0.000, and y = 6.25 +0.96x, where x represents the IQ score of the younger child. Find the best predicted value of y given that the younger child has an IQ of 101? Use a significance level of 0.05. Click the icon to view the critical values of the Pearson correlation coefficient r. The best predicted value of ŷ is. (Round to two decimal places as needed.)
A local brewery distributes beer in bottles labeled 32 oz. believing the SD=1.5. A government agency thinks that the bottles are not correct. The agency selects 50 of these bottles, measures their contents, and obtains a sample mean of 32.4 oz. Test at the 0.03 significance level. 1. The graph is (give one answer: L - Left tailed, R - Right tailed, 2 - Two-Tailed) 2. Critical Value (start with negative and separate with a comma if there are 2) 3. Test statistic 4. The 3-decimal p-Value 5. Test statistic is where compared to CV? (Give a letter: L - Left, M - Middle R - Right)
Qualitative researchers should view the opinions of other researchers about the themes derived from data analysis as biased. This is because other researchers would not be as familiar with the results as the researcher. True False A researcher has conducted a crosstabs analysis to understand the distribution of income across 3 different gender groups (male, female and non-binary). They notes that the Chi-square test produced an asymptotic significance level of 0.027. What does this suggest? (pick the most appropriate interpretation) Income does not vary across different genders Income does not differ across the different grouops There are significant differences in the distribution of income for the male, female and non-binary groups The male group has sufficiently more income compared to the female and non-binary groups

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"

Describe a study in which you can use both nonparametric and parametric statistics. A researcher has participants expecting to receive either painful or mild electrical shocks during a study wait in a quarter-full waiting room with other participants. He then measures whether they choose to sit next to other participants or if they sit far away on their own. What is the best test to run for this study and why?
Which of the following measures are most resistant to outliers? Mean Median Mode Range Standard Deviation IQR (interquartile range)
I am unsure how to complete this graph, any help would be great, thank you.
