stats question The researchers from a study interviewed two random samples, one in 2015 and one in 2018. Both samples were asked, "Have you read a print book in the last year?" The accompanying results from the study are presented in the table below:| Read a print book | 2015 | 2018 | Total ||-------------------|------|------|-------|| Yes | 1212 | 1325 | 2537 || No | 712 | 689 | 1401 || Total | 1924 | 2014 | 3938 |**Tasks:****a. Find and compare the sample proportions that had read a print book for these two groups.**The sample proportion of the 2015 subjects that read a book within the last year is **0.6299**. The sample proportion of the 2018 subjects that read a book within the last year is **0.6579**. (Rounded to four decimal places as needed.)The sample proportion for 2015 is **less than** the sample proportion for 2018.**b. Find a pooled estimate of the sample proportion.**A pooled estimate of the sample proportion is calculated based on the total number of 'Yes' responses over the total number of respondents for both years. *Round to four decimal places as needed.*

The best estimate of p is obtained by pooling the data to get the proportion of successes in both samplescombined; that is, we estimate p by We call p^p the pooled sample proportion.p^p=1212+13251924+2014=25373938=0.6442 Therefore the pooled estimate of sample proportion is 0.6442
