Complete Question

A population has a mean mu μ equals = 77 and a standard deviation σ = 14. Find the mean and standard deviation of a sampling distribution of sample means with sample size n equals = 26

Answer:

The mean of sampling distribution of the sample mean ( \= x) is \mu_{\= x } =  77

The standard deviation of sampling distribution of the sample mean ( \= x) is  

    \sigma _{\= x} = 2.746

Step-by-step explanation:

From the question we are told that

    The population mean is  \mu  =  77

     The  standard deviation is  \sigma =  14

     The sample size is  n  =  26

     

Generally the standard deviation of sampling distribution of the sample mean ( \= x) is  mathematically represented as

           \sigma _{\= x} =  \frac{ \sigma }{ \sqrt{n} }

substituting values  

          \sigma _{\= x} =  \frac{  14}{ \sqrt{26} }

          \sigma _{\= x} = 2.746

Generally the mean of sampling distribution of the sample mean ( \= x) is  equivalent to the population mean i.e  

      \mu_{\= x } =  \mu

      \mu_{\= x } =  77

hram777 [196]

-(2x+4)= 18

Divide -

2x+4= -18

Subtract 4

2x= -22

Divide 2

x= -11

-(2(-11)+4)= 18

18= 18

A.)ii. and iii.<br> B.)ii.<br> C.)i.<br> D.)i. and iv.
Vlad [161]
The answer is B) ii

The notation "p --> q" means "if p, then q". For example

p = it rains
q = the grass gets wet

So instead of writing out "if it rains, then the grass gets wet" we can write "p --> q" or "if p, then q". The former notation is preferred in a math class like this. 

So when is the overall statement p --> q false? Well only if p is true leads to q being false. Why is that? It's because p must lead to q being true. The statement strongly implies this. If it rained and the grass didn't get wet, then the original "if...then" statement would be a lie, which is how I think of a logical false statement. 

If it didn't rain (p = false), then the original "if...then" statement is irrelevant. It only applies if p were true. If p is false, then the conditional statement is known to be vacuously true. So this why cases iii and iv are true.
