A sample of 100 LED TVs is taken at random. Out of 100 we found 35 TVs are of Sony, 50 are of LG and 15 are of Samsung. The point estimate of population proportion of LG is

For the following data:

The sample statistic t follows t-distribution with 'm' degrees of freedom, then m is equal to

The sampling distribution of the sample mean approaches a normal distribution as the sample size gets larger, no matter what is the shape of the population distribution.

The above statement is:

Match List-I with List-II

Choose the correct answer from the options given below:

The point estimate of the population standard deviation for the random sample 5, 8, 10, 7, 10, 14 is:

If X is normally distributed with mean 30 and standard deviation 5, the value of $P(26 \le X \le 34)$ is: (Where $P(0 \le Z \le 0.8) = 0.2881$)

If the sample size is 45, then the degree of freedom is equal to
