You are conducting a study to see if the proportion of women over 40 who regularly have mammograms is significantly less than 0.69. You use a significance level of α=0.10       H0:p=0.69       H1:p<0.69 You obtain a sample of size n=427n=427 in which there are 263 successes. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic =  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) α
