if sample size n very large and probability tends to 0.5
if these both conditions are satisfied by binomial distribution it would tends to normal distribution

sravani

n tends to infinite i.e large
Probability tends to 0 i.e indefinitely small.
np = lamda

Anji

the above is poison to Bin

Anji

no of trails n tends to indefinitely large..i.e infine
neither p nor q is very small
Then bin tends to normal

if the death of of the snow is my yard is normally distributed with the m is equals to 2.5 and
what is the probability that a randomly chosen location with have a no that between 2.25 and 2.76

A consumer advocate agency wants to estimate the mean repair cost of a washing machine. the agency randomly selects 40 repair cost and find the mean to be $100.00.The standards deviation is $17.50. Construct a 90% confidence interval for the mean.

Sixty-four third year high school students were given a standardized reading comprehension test. The mean and standard deviation obtained were 52.27 and 8.24, respectively. Is the mean significantly different from the population mean of 50? Use the 5% level of significance.

Simple Bar Chart is a Diagram which shows the data values in form of horizontal bars. It shows categories along y-axis and values along x-axis. The x-axis displays above the bars and y-axis displays on left of the bars with the bars extending to the right side according to their values.

add all the data and divide by the number of data sets. For example, if test scores were 70, 60, 70, 80 the total is 280 and the total data sets referred to as N is 4. Therfore the mean or arthritmatic average is 70. I hope this helps.
