Answer:
isn't it i96
Step-by-step explanation:
because you have 97 I's and you are taking one away... So, yeah, i96... Unless I am wrong. Then, I am sorry hehe
Unless you mean i^97. Then, it is 0 because i^97 is just i and i - i =0
Answer:
Option C
Step-by-step explanation:
The central Limit Theorem says the sampling distribution of the sample mean is approximately normal under certain conditions
The conditions are
i) the population should be symmetrial. If population is skewed sample size should be sufficiently large atleast 30
ii) Samples should be drawn strictly at random
iii) the sample observations should be independent
Thus we find that option a is not necessary because even for skewed large sample size allows the theorem
Option b is not correct since if population is less than 30, sampling itself is not necessary.
Option d is also wrong since normality is not necessary
Only option C) The sample size must be large (e.g., at least 30) is the necessary condition
Not enough information to help with.
