A researcher wants a point estimate of the population mean daily screen time μ\mu for all adults in a state. She selects a simple random sample of 100 adults from the state and computes the sample mean xˉ\bar{x}. She then reports the point estimate 2xˉ2\bar{x} (twice the sample mean) to "account for multitasking." Which statement describes whether 2xˉ2\bar{x} is biased for μ\mu?
