Answer:
The point estimate of the difference in the population proportion of men and women who agreed is 0.005.
Explanation:
In statistic, point estimation comprises of the use of sample data to estimate a distinct data value (known as a point estimate) which is to function as a "best guess" or "best estimate" of an unidentified population parameter.
The point estimate of the population mean (<em>µ</em>) is the sample mean ().
Similarly the point estimate of population proportion (<em>p</em>) is the sample proportion ().
In this case we need to estimate the point estimate of the difference in the population proportion of men and women who agreed.
The point estimate of the difference in the population proportion of men and women who agreed will be the difference between the sample proportions.
The sample proportion of men who agreed that they felt science makes our lives healthier, easier and more comfortable is,
The sample proportion of women who agreed that they felt science makes our lives healthier, easier and more comfortable is,
Compute the difference between the two sample proportions as follows:
Thus, the point estimate of the difference in the population proportion of men and women who agreed is 0.005.
