Answer:
Mean 24, standard error 0.8
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean 
and standard deviation 
, the sample means with size n of at least 30 can be approximated to a normal distribution with mean and standard deviation, also called standard error 
In this problem, we have that:
What are the mean and the standard error of the sample mean?
By the Central Limit Theorem, mean 24 and standard error 
32 is 32.4543611% 0f 98.6
Answer:
A
Step-by-step explanation:
the first part is definetly triangle b is a reflection of triangle a across the x axis i can't see the bottom part of the last answer but I'm pretty sure A would be correct because triangle c may be a rotation but it's most likely not a reflection of triangle a
A disjunction is a compound statement formed by joining two statements with the connector OR. The disjunction "p or q" is symbolized by p q. A disjunction is false if and only if both statements are false; otherwise it is true. The truth values of p q are listed in the truth table below.
Answer:
-2.5
Step-by-step explanation:
-30 + (-15) + (-20) + 55 = -10. Then you divide it by how many numbers there are (4). Which equals - 2.5. If this is wrong, then round up to -3.
