Suppose a random sample of n = 300 teenagers 13 to 17 years of age was asked if they use social media. Of those surveyed, 215 stated that they do use social media. Find the sample proportion of teenagers 13 to 17 years of age who use social media. The sample proportion is $p = \Box$. (Round to three decimal places as needed.) Clear all Check answer

A certain population follows a Normal distribution with mean $\mu$ and standard deviation $\sigma = 2.5$. You collect data and test the following hypotheses: $$H_0: \mu = 1$$ $$H_A: \mu \neq 1$$ You obtain a p-value of 0.082. Which of the following statements is TRUE? A 95% confidence interval for $\mu$ will include the value 1. A 95% confidence interval for $\mu$ will include the value 2.5. A 90% confidence interval for $\mu$ will include the value 2.5. A 90% confidence interval for $\mu$ will include the value 1.
