Answer:
H0 : p = 0.5
H1 : p ≠ 0.5
Two tailed test
Step-by-step explanation:
The test if the true proportion of heads is different from 50%; this means the initial truth, that is the true proportion is 50% ; which is the null ;
H0 : p = 0.5
The researcher intends to test if the true proportion is not 50% ; that is the researcher is n spwcudfic about if the proportion is lower or higher, he just wants to test that the proportion is different, hence the test could go either way ;
Alternative hypothesis ;
H1 : p ≠ 0.5
Since the sign in the alternative hypothesis could be in either direction, then we have a two tailed test
Answer:
5+2n=7
Step-by-step explanation:
5+2n=7
7-5=2n
2=2n
2÷2=1
n=1
If a > 0, b>0, show that f(x)= a(1-e^-bx)
The slope is
and the y intercept is -1
so the equation is y =
x-1
Whenever there is no exponent on a variable,
you can give it an exponent of 1.
So we can rewrite the x's in this problem as x¹.
When we multiply two terms together
with like bases, we add their exponents.
So now just add their exponents to get x².
