When the Titanic sank, passenger survival rates were recorded along with additional information like their name, what class ticket they had, their age, and whether or not they had children. Some of these factors may predict whether or not a passenger was likely to survive the accident. The data set "Titanic survival.jasp" contains actual recorded data from the event. Using the variables "Class" and "Survived", conduct a Chi-Square Test for Independence, at alpha = 0.05, to see if a passengers ticket class (first, second, or third class) is significantly associated with their survival rates. Identify the correct value for df. A. 2 B. 1309 C. 4 D. 127
A researcher wishes to test the claim that, on average, more juveniles than adult are classified as missing person.

An investigator analyzed the leading digits from 794 checks issued by seven suspect companies. The frequencies were found to be 218, 130, 106, 83, 65, 48, 48, 37, and 59, and those digits correspond to the leading digits of 1, 2, 3, 4, 5, 6, 7, 8, and 9, respectively. If the observed frequencies are substantially different from the frequencies expected with Benford's law shown below, the check amounts appear to result from fraud. Use a 0.025 significance level to test for goodness-of-fit with Benford's law. Does it appear that the checks are the result of fraud?

Q1)The following is true, except: a)Data transformations can be used to improve the normality status of your data (e.g. log transformation) b)We need to assess normality prior to doing hypothesis testing, especially when the sample size is small . c)QQ plots gives a very good indication of normality, when the scattered points are on the diagonal line (closer to a straight line), this suggests lack of normality. d)When having significant results of Shapiro-Wilk test, we have sufficient evidence to reject the NULL hypothesis (i.e. normal distribution) in support of the alternative f)The variability of the data should be regarded as noise, and thus ignored

Researchers wanted to determine whether fence lizards learned to avoid fire ants. To determine this, they gathered lizards from eastern Arkansas (where there were no fire ants), and from southern Alabama (which had been invaded by fire ants). The lizards were then exposed to fire ants, and researchers measured how long (in seconds) it took the lizards to flee. Suppose that mu_I is the average time to flee for a lizard that lives in the invaded areas in Alabama, and mu_U is the average time to flee for a lizard living in the uninvaded areas of Arkansas. The researchers are interested in understanding if lizards from invaded areas are faster to flee when exposed to ants. What should they use for their hypotheses? H0:μI−μU= HA:μI−μU What are the hypothesis and null hypothesis answers? And how did you get the hypothesis and null hypothesis without any numbers?
