Step-by-step explanation:
After a recent survey of 1485 people aged 18 to 24 showing that 78% were impressed with the special effects on a newly released movie, a statistician decided to test a claim by the film company stating that more than 80% of all people aged 18 to 24 who went to see the movie were impressed with the special effects. Using a 0.05 significance level, find the P-value and determine an initial conclusion about the claim. A. 0.0268; reject the null hypothesis B. 0.9732; fail to reject the null hypothesis C. 0.0268; fail to reject the null hypothesis D. 0.9732; reject the null hypothesis
(B Fail to reject the null hypothesis. The P-value is greater than the level of significance.
What is the null hypothesis?The null hypothesis is a common arithmetic theory that asserts that no statistical relationship or significance exists between two sets of observed data and measured phenomena in a set of given, single, observed variables.
The null hypothesis is rejected, if the P-value is less than the level of significance.
Here, it is provided that the test is left-tailed and the z score is -1.23.
From, the table of the negative scores, the P-value for the left-tailed test is 0.1093.
Since the P-value (0.1093) is greater than the level of significance (0.05). The null hypothesis is not rejected.
Hence, the correct option is (B), Failing to reject the null hypothesis. The P-value is greater than the level of significance.

1/4=3/12 2/3=6/12
Answer:
2/3 = 8/12
Step-by-step explanation:
1/4 is equal to 3/12, because 1/4 times 3/3 (which is 1) equals to 3/12.
2/3 is not equal to 6/12, because 6/12 can be simplified to 1/2. 2/3 is greater than 1/2, not equal to half. So, 2/3 times 4/4 (which is 1) equals to 8/12.
