It was claimed currently that more than 50% of high school students in United States use computers for educational purposes. We wish to examine this claim. We select a random sample of 200 U.S. high school students and find out that 105 of these students employ computers for educational purposes. Based upon this, can we conclude, at the 0.1 level of significance, that more than 50% 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.
