Researchers wondered if there was a difference between males and females in regard to some common annoyances. They asked a random sample of males and females, the following question: "Are you annoyed by people who repeatedly check their mobile phones while having an in-person conversation?" Among the 564 males surveyed, 184 responded "Yes"; among the 546 females surveyed, 202 responded "Yes." Does the evidence suggest a higher proportion of females are annoyed by this behavior? Complete parts (a) through (g) below. (d) Describe the sampling distribution of premale -Pmale: Draw a normal model with the area representing the P-value shaded for this hypothesis test. The sampling distribution is approximately normal with mean 0 and standard deviation 0.0286. (Type an integer or decimal rounded to four decimal places as needed.) Draw a normal model with the area representing the P-value shaded for this hypothesis test. Choose the correct graph below, where the horizontal axis represents Pfemale Pmale O A. O B. Oc. 0.044 0.044 -0.044 0. -0.044 (e) Determine the P-value based on the model from part (d). First find the test statistic for this hypothesis test. (Round to two decimal places as needed.) and then click Check Answer

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.
