Test theresearch hypothesis that Candidate A’s approval rating is greater than 50% against the null hypothesisthat it is 50%, with α=0.05.(a) Check the assumption for the hypothesis testing.(b) State the null hypothesis and alternative hypothesis.This my third time posting the same question. Because no one answer it straight to me. I already answered the question. Could you please tell me which one of these are not correct. and if so Could you please tell me the correct answer first then explain it. Also could you please highlight the correct answer for each oneIt has recently been claimed that 25% of adults consider spring to be their favorite season of the year. A researcher is skeptical of this claim and believes this percentage to be too low. She surveys a random of 1000 adults and find that 390 of these adults consider spring to be their favorite season of the year. As she prepares to conduct a hypothesis test, the researcher writes out her alternative hypotheses as P< 0.25 what is wrong with this? The alternative hypothesis should be p<0.39 The alternative hypothesis should be p>0.39 The alternative hypothesis should bep>0.25 The alternative hypothesis should bep=0.25
- Please show step by step work: An original claim is made that 60% of American consumers are not comfortable with the use of drone delivery for merchandise. Hypothesis testing results in Rejection of the Null hypothesis. Using Figure 8-5 on page 366 of the text, clearly state the final conclusion reached from this hypothesis test.A survey was conducted to investigate trends of romantic relationships and online behaviors.

- what is the null hypothesis statement and alternative hypothesis statement of the first one?Kenya is a behavioral psychologist who works with children on the Autism Spectrum. She suggests that blowing bubbles may effect children's eye contact (she hasn't predicted if it would increase or decrease). She works with a student who makes 5 points of eye contact in a session. How would the NULL hypothesis be state for her study using bubbles? µ < 5 µ = 5 µ > 5 µ ≠ 5Researchers compared the balance of a sample of elderly (E) patients with that of a separate sample of younger (Y ) patients. They exposed members of each age group to unpredictable noises and measured the amount of forward and backward sway. To test whether the elderly tend to sway more, they should choose which pair of hypotheses?
