In a 2013 poll, it was found that 0.78 of Americans cover their mouth when sneezing. A sociologist claims that this proportion has decreased since then. She wishes to test the following claim (H1) at a significance level of a 0.10. Ho: p = 0.78 H₁: p<0.78 She obtains a random sample of 21 Americans and finds that 13 cover their mouth when sneezing. The p-value for this test is the probability of observing... at most 13 Americans cover their mouth when sneezing. O at least 13 Americans cover their mouth when sneezing. What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value = The p-value is... less than (or equal to) a esc K 1 2 7 C $ 54 #3 e a W e S 925 % 言 ווב 6 & 7 d g y
