7. It is claimed by an advertisement that 4 out of 5 kids have energy gap. To test this, a random sample of 250 children were tested if they experienced this `energy gap.' It was found out that 202 of them is experiencing it. What is the null and alternative hypothesis of the test? a. Ho: p ≠ 0.80 versus Ha: p = 0.80 b. Ho: p > 0.80 versus Ha: p < 0.80 c. Ho: p = 0.80 versus Ha: p ≠ 0.80 d. Ho: p = 0.80 versus Ha: p < 0.80
