What is mode mean?

Mean is the sum of all the numbers added and divied by the amount of nunbers. for ex. if 1,7,9,9,4 were your numbers then you would add them all together witch is 30 . then you would divied it by 5 because that is the amount of numbers you started with. so the anser would be 6 and that is the average between 1 and 9

mode is like a trend in this nunber 1,7,9,9 and 4 is your starting number. and there are two 9s so the mode would be nine and if the number is 1,7,9,9,9,4 then the the mode would stay because even thouth there are three nines it still stays the same.and if the number was 1,7,7,9,9,4 then the mode would be 7 and 9 because there are two sevens and two nines.

.01 criterion of significance what is the percent type you error?

I believe you are asking about hypothesis testing, where we choose an alpha value, (also called a signifance level). Thus, I will rephrase your question as follows: If I choose an alpha value of 0.01, what percent of time do you expect the come to an erroneous conclusion, that is test statistic to fall out of the critical region yet the null hypothesis is true? The answer is 1% of the time, an incorrect rejection of the null hypotheis, which is a type I error.

Will the distribution of the sample means follow the uniform distribution?

The distribution of the sample means will, as the sample size increases, follow the normal distribution. This is true for any given distribution (e.g. does not need to be a normal distribution). This concept is from the central limit theorem. It is one of the most important concepts in statistics, along with the law of large numbers. An applet to help you understand this concept is located at: http:/www.stat.sc.edu/~west/javahtml/CLT.html
