esc 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 0.001. = Ho: p = 0.78 H₁: p<0.78 She obtains a random sample of 10 Americans and finds that 7 cover their mouth when sneezing. The p-value for this test is the probability of observing... O at most 7 Americans cover their mouth when sneezing. O at least 7 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... O less than (or equal to) a O greater than a This test statistic leads to a decision to... O reject the null O accept the null O fail to reject the null W G
