Answer:
Step-by-step explanation:
The type I error occurs when the researchers rejects the null hypothesis when it is actually true.
The type II error occurs when the researchers fails to reject the null hypothesis when it is not true.
Null hypothesis: The proportion of people who write with their left hand is equal to 0.23: p =0.23
Type I error would be: Fail to reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is actually different from 0.29
Since 0.29 is assumed to be the alternative claim.
Type II error would be: Reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is actually 0.29
Still with the assumption that 0.29 is the alternative claim.
 
        
             
        
        
        
Log x+ log 7= log 42
log x=log 42 - log 7
log x=log 42/7                [  log a -  log b= log (a/b)   ]
log x= log 6
therefore:
x=6
Answer: x=6
        
             
        
        
        
1. -4
2. 2
four plus negative four is zero and two minus two is zero
        
             
        
        
        
Answer:
The product of  is
 is 
Step-by-step explanation:
We need to find the product of 
Using the exponent rule: 
So, 

Applying above rule:


So, the product of  is
 is
