Answer #1

Given:

Sample size, n = 888

The number of patients taking a prescription drug daily, x = 23

Population proportion, p0 = 0.021

Significance level, \alpha = 0.1

Sample proportion, Ⓡ = 24 = 23 = 0.0259 888 npoll-Po) = 888X0.021 (1-0-021) 18.26 >10 Because npoci-pol – 18.26 · 10 , the sa

As p value is greater than significance level 0.1, we fail to reject the null hypothesis and conclude not more than 2.1% of this drug's users experience flulike symptoms as a side effect.
