A A 3) Margin of error: 0.004; confidence level: 95%; p and q unknown ^ 4) Margin of error: 0.009; confidence level: 99%; p and q unknown ^ 5) Margin of error: 0.01; confidence level: 95%; from a prior study, p is estimated by the decimal equivalent of 52%. 3) 4) 5)

The table below shows the distribution of weight of a certain type of fruit. weight frequency <10 4 <15 3 <20 23 <25 54 <30 16 <35 9 <40 7 <45 4 1) Draw the histogram of the data and use it to estimate the model weight. 2) calculate mean, median and interquartile range.

Determine the minimum sample size required when you want to be 95% confident that the sample mean is within two units of the population mean and = 4.3. Assume the population is normally distributed. n =

In spite of the potential safety hazards, some people would like to have an Internet connection in their car. A preliminary survey of adult Americans has estimated this proportion to be somewhere around 0.30. Use the given preliminary estimate to determine the sample size required to estimate this proportion with a margin of error of 0.05.

The pulse rates of 162 randomly selected adult males vary from a low of 42 bpm to a high of 102 bpm. Find the minimum sample size required to estimate the mean pulse rate of adult males. Assume that we want 98​% confidence that the sample mean is within 2 bpm of the population mean. Complete parts​ (a) through​ (c) below.       a. Find the sample size using the range rule of thumb to estimate

what is the population of focus? a reasearch is being done to determine canopy spread of a type of MATURE tree in a given location.   the location has 40,000 of these and the mature trees are estimated at 10feet tall. the research collected spread from 1000 random mature trees.
