During the 2007–2008 decline in the housing market, it appeared
that the average size of a newly constructed house fell. To investigate
this trend, the square footages of a random sample of houses built in
2008 were compared to houses built in 2018. A random sample of 45
homes built in 2008 had a sample mean of 2,462.3 square feet and a
sample standard deviation of 760.8 square feet. A random sample of
40 homes built in 2018 had a sámple mean of 2,257.0 square feet and
a sample standard deviation of 730.2 square feet. Assume that the
population variances for the square footages of houses built in these
two years are equal. Using a = 0.05, perform a hypothesis test to
determine if the average home constructed in 2010 was larger than a
home built in 2018 and construct a 95% confidence interval to estimate
10.

constructed in these two years. Interpret your result.

Please do not give solution in image format thanku Do our children spend enough time enjoying the outdoors and playing with friends, or are they spending more time glued to the television, computer, and their cell phones? A random sample of 250 youth between the ages of 8 and 18 showed that 160 of them had a TV in their bedroom and that 90 had a video game console in their bedroom. Estimate the proportion of all 8- to 18-year-olds who have a TV in their bedroom and calculate the 95% margin of error for your estimate. (Round your margin of error to three decimal places.)
