It was determined that the percentage of t's in the English language in the 1800s was 6%. A random sample of 500 letters from a current newspaper contained 24 t's. Test the hypothesis that the proportion of t's has changed in modern times, using the 0.05 level of significance. Treat the newspaper as a random sample of all letters used. O E. Ho: p*0.06 H p=0.06 Determine the z-test statistic. z= (Round to two decimal places as needed.) Find the p-value. p-value = (Round three decimal places as needed.) Choose the correct conclusion. O A. Do not reject Ho. The proportion of t's is not significantly different from 0.06. O B. Reject Ho. The proportion of t's is not significantly different from 0.06. Oc. Do not reject Ho. The proportion of t's is significantly different from 0.06. O D. Reject Ho The proportion of t's is significantly different from 0.06.
