Determine the necessary sample size for the following examples: A) A senator wants an estimate of the proportion of the population who support her education views. She wants the estimate to be within .013 of the true proportion. Assume a 95 percent level of confidence. B) 45 percent of tourists going to Las Vegas go to a concert. The Las Vegas tourism board wants to update this percentage. For the new study, the estimate should be within 2% of the...

1. In order to determine the size of a home-heating furnace, it is necessary to estimate the heat loss during the coldest day in winter. Provide the rates of heat loss per unit surface area for the following surfaces commonly encountered in house construction. You may assume an inside air temperature of 25°C, an outside temperature of -5°C, and heat transfer coefficients of 20 Wm-2K-1 and 5 Wm-2K-1 between air and the outside and inside surfaces, respectively. The thermal conductivities...

Find the sample size necessary to estimate the mean IQ score of statistics students such that it can be said with 95% confidence that the sample mean is plus or minus3 IQ points of the true mean. Assume that the standard deviation is 15 and determine the required sample size. 2) In a survey of 2,416 adults, 1,876 reported that e-mails are easy to misinterpret, but only 1,231 reported that telephone conversations are easy to misinterpret. Complete parts (a) through...

Determine the sample size necessary for estimating the proportion of Ohio teachers that feel anxious about teaching online. Suppose you want to be 99% confidence that the proportion is within 4.25 percentage points of the true proportion. Furthermore, suppose a study from a few years ago showed that 72% of Ohio teachers feel anxious about teaching online.
