The results indicated that 58% of the females and 51% of the males answered window tinting. The sample sizes of males and females were not provided. Suppose that of 600 females, 348 reported window tinting as their preferred luxury upgrade of choice, while of 400 males, 204 reported window tinting as their preferred luxury upgrade of choice. Complete parts (a) through (d) below. a. Is there evidence of a difference between males and females in the proportion who said they prefer window tinting as a luxury upgrade at the 0.05 level of significance? State the null and alternative hypotheses, where π1 is the population proportion of females who said they prefer window tinting as a luxury upgrade and π2 is the population proportion of males who said…

The new weight-loss supplement was less effective on ▼(Choose one) in the study. That is because % of them failed to lose weight after two weeks, whereas only % of the ▼(Choose one) failed to lose weight after two weeks.
In a science fair project, Emily conducted an experiment in which she tested professional touch Ktherapists to see if they could sense her energy field. She flipped a coin to select either her right hand or her left hand, and then she asked the therapists to identify the selected hand by placing their hand just under Emily's hand without seeing it and without touching it. Among 357 trials, the touch therapists were correct 169 times. Complete parts (a) through (d). S View an example Get more help. 4- & 87 U 0.5 (Type an integer or a decimal. Do not round.) b.
