The first 7 or the second one ?
Answer:
The answer in the procedure
Step-by-step explanation:
we have

Prove the identity
In this problem there is a mistake: in order to obtain an identity the second denominator at the left side must be 1 + cosx
so

Adds fraction in the left side

Remember that

and


substitute

Multiply both sides by sin(x)


----> identity verified

Answer:
The null hypothesis will be rejected
Step-by-step explanation:
The null hypothesis is that people who favour ban on stem cell research is less than or equal to 0.61
The alternate hypothesis is that people who favour ban on stem cell research is greater than 0.61
Proportion of population = 0.61
Total events = 360
Sample size = 554
Sample proportion = 360/554 = 0.649
As per test statistics –
Z = (p-p0)/sqrt {(p0 (1-p0))/n} = (0.649 -0.61)/ {(0.61 (1-0.61))/554}
= 0.039/0.021
= 1.857
P (Z<1.857) = 1- P (Z<1.857) = 1-0.9664 = 0.0336
So alpha value is 0.064.
Thus, we will reject the null hypothesis
