- Shannon conducts a study and tells you that when she calculated Cohen's d , it was 0.00. What conclusion would you reach about the effects of her independent variable?For a population with μ = 60 and σ = 8, the X value corresponding to z = -0.50 would be?For a population with u=50 and o=10,what is the x value corresponding to z=0.4?
- How would you figure out b,c & e?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. When the data is loaded into the correct tool in StatKey, and the "Generate 1000 samples" button is clicked, here is what StatKey generates:- see image. The researchers observed that the lizards from Alabama had an average response time of 32 seconds, and the lizards from Arkansas had an average response time of 44 seconds. Using this, which of the following is closest to the P-value for this hypothesis test? What conclusions can we make…Researchers wanted to determine whether fence lizards learned to avoid fire ants.

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?
