Drowning in bathtubs is a major cause of death in children less than 5 years old. A random sample of 148 parents was asked many questions related to bathtub safety. Overall 85% of the sample said they used baby bathtubs for infants. Estimate the percent of all parents of young children who use baby bathtubs.

≥ 85%

Step-by-step explanation:

n ( sample size ) = 148

0.85 used baby bathtubs

0.15 do not use bathtubs

Determine the percent of parents of young children using Baby bathtubs

P ( n > 0.85 )

let n ( 148 ) represent all parents of young children the estimate of parents using baby bathtub ≥ 85%

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
