2. the thermal inertia properties of concrete used as a building material were studied. five samples of the material were tested in a structure, and the average interior temperatures (c) were reported as follows: 23.01, 22.22, 22.04, 22.62, and 22.59. assume that the interior temperature is normally distributed and the significance level,  is 0.05. a. test whether the average interior temperature equals 22.5 or not by following the steps of hypothesis testing, i. e., state the null and alternative hypotheses, write and calculate the appropriate test statistic, compare to the critical value, write your conclusion. b. construct a 95% confidence interval for the population mean . can you use the resulting confidence interval to answer part (a)? explain.

step-by-step explanation:

the shape,the size and the distance

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
