Transcribed Image Text:For each of the studies presented below: (1) Define the population
parameter of interest to the researchers and (2) Estimate the population
parameter defined in (1), with a point estimate.
(a) A 42-inch, large-screen, plasma TV is designed to consume only
350 watts and therefore produce less heat. In order to check this
specification, a sample of plasma TVs was obtained and the power
consumption was measured for each. The sample mean power
consumption was 353.8 watts.
(b) A sports physiologist is interested in the proportion of profes-
sional marathon runners who have very high haemoglobin counts.
To this end, the researcher randomly selects 150 elite marathon
runners, measures their haemoglobin levels and records it as either
very high or normal. The researcher found that 48 subjects in the
sample had very high haemoglobin counts.
