Translate the statement into a confidence interval. Approximate the level of confidence. in a survey of 1032 adults in a country, 73% said being able to speak the language is at the core of national identity. The survey's margin of error is ±3.9%E The confidence interval for the proportion is (

A sample of n = 200 college students are asked if they believe in extraterrestrial life and 120 of these students say that they do. The data are used to test if more than half of college students believe in extraterrestrial life. d. Find a 95% confidence interval   e. Write a conclusion for the confidence interval

A survey asked, "How many tattoos do you currently have on your body?" Of the 1233 males surveyed, 183 responded that they had at least one tattoo. Of the 1042 females surveyed, 139 responded that they had at least one tattoo. Construct a 95% confidence interval to judge whether the proportion of males that have at least one tattoo differs significantly from the proportion of females that have at least one tattoo. Interpret the interval. C Let p₁ represent the proportion of males with tattoos and p2 represent the proportion of females with tattoos. Find the 95% confidence interval for p₁ -P2- The lower bound is The upper bound is (Round to three decimal places as needed.)

Use the histogram below to build a 95% confidence interval of the average heart rate of a person. Put your two numbers below in the spaces provided. Round to one decimal: ex: 98.2 The histogram visualizes the results of doing one thousand studies just like above. We are 95% confident that the average heart rate of a person is between ____and_____ All information needed to answer this problem is present. There is no missing information to this question.

Construct the indicated confidence interval for the difference in proportions. Assume that the samples are Independent and that they have been randomly selected. A survey of randomly chosen adults found that 45% of the 231 women and 61% of the 275 men follow regular exercise programs. Construct a 95% confidence interval for the difference in the proportions of women and men who have regular exercise programs. O A. (-0.165, -0.155) OB. (0.052, 0.268 ) OC. (-0.246, -0.074) O D. (-0.267, -0.053) O E. (-0.250, -0.070 )
