Answer:
a) true
Step-by-step explanation:
Decision Rule
If;
P-value > significance level --- accept Null hypothesis
P-value < significance level --- reject Null hypothesis
Z score > Z(at 95% confidence interval) ---- reject Null hypothesis
Z score < Z(at 95% confidence interval) ------ accept Null hypothesis
For the case above, the p-value for the test is 0.047 which is less than the significance level 0.05
P-value < 0.05
Using the decision rule, we will reject the Null hypothesis which is the same as stated in the question, which means its true.
_Confirmed._

Answer:
Step-by-step explanation:
Given: A fair coin is tossed 5 times in a row.
Total outcomes=2×2×2×2×2=32 [total outcomes in a coin is 2]
Let A be the event of getting heads exactly 2 times
Then the favorable outcomes=
Then probablity of getting heads exactly 2 times =
