Baby walkers are seats hanging from frames that allow babies to sit upright withtheir legs dangling and feet touching the floor. Walkers have wheels on their legsthat allow the infant to propel the walker around the house long before he or she canwalk or even crawl. Typically, babies use walkers between the ages of 4 months and11 months.Because more walkers have tray table in front that block babies’ view of their feet,child psychologists have begun to questions whether walkers affect infants’cognitive development. One study compared mental skills of a random a=sample fothose who used walkers with a random sample of those who never used walkers.Mental skill scores averaged 113 for 54 babies who used walkers (standard deviationof 12) and 123 for 55 babies who did not use walkers (standard deviation of 15). (A) Is there evidence that the mean mental skill score of babis who use walkers is different from the mean mental skill score of babies who do not use walkers? Explain your Answer.
answer part 2 frq styed please and show work 1. Because of the constantly evolving political climate around the United States, Gallup (who regularly conducts polls in the U.S.) conducted a poll just after the inauguration asking U.S. adults if they approve of the initiatives President Biden had implemented in his first few days in office. Another Gallup poll was conducted now that President Biden has been in office for a month asking U.S. adults if they approve of the initiatives President Biden had implemented after his first month in office. According to the first Gallup poll of 1500 randomly selected U.S. adults, 64% approved of the initiatives President Biden had implemented in his first few days in office. And according to the second Gallop poll of 1700 U.S. adults, 54% approved of the initiatives President Biden had implemented after his first month in office. Construct and interpret a 95% confidence interval for the change (difference) in the true proportion of U.S. adults…

They have three assembly lines, “Razor,” “Blazer,” and “Tracer,” named after the particular dune buggy models produced on those lines. Each assembly line was originally designed using the same target production rate. However, over the years, various changes have been made to the lines. Accordingly, management wishes to determine whether the assembly lines are still operating at the same average hourly production rate. Production data (in dune buggies/hour) for the last eight hours are as follows. (You may find it useful to reference the F table.)
