Extracted text: It was claimed recently that more than 55% of high school students in the United States use computers for educational purposes. We wish to examine this claim. We choose a random sample of 225 U.S. high school students and find that 133 of these students use computers for educational purposes. Based on this, can we conclude, at the 0.05 level of significance, that more than 55% of high school students in the United States use computers for educational purposes? In your answers, denote the proportion of all U.S. high school students who happen to use computers for educational purposes by p. Perform a one-tailed test. Then complete the parts below.
