Consider the following to answer the question(s) below:
An advertising agency has developed a new ad for one of the national car manufacturing companies. The agency is interested in testing whether the proportion of favourable responses to the ad is the same between male versus female adults. It plans on conducting the test using an alpha level equal to 0.05. A sample of 100 adults of each gender will be used in the study. Each person will be asked to view the ad and indicate whether they find the ad to be "pleasing" or not. The samples resulted in 57 males and 47 females that liked the ad.
-The appropriate null and alternate hypotheses are

• A) H0 : p1 = p2 and HA : p1 ≠ p2
• B) H0 : p1 = p2 and HA : p1 > p2
• C) H0 : p1 > p2 and HA : p1 ≠ p2
• D) H0 : p1 ≠ p2 and HA : p1 = p2
• E) H0 : p1 = p2 and HA : p1 < p2

Definitions:

Transmission Output Shaft

The shaft that transmits power from the transmission to the drive wheels.

Driveshaft Vibration

Unwanted oscillations of the driveshaft, often due to imbalance or misalignment, that can lead to driveability issues or damage.

U-joint Operating Angles

U-joint Operating Angles refer to the angles at which universal joints (U-joints) operate, connecting rotating shafts in a drive system, crucial for efficient power transmission and reducing wear.

Out-of-Balance

Refers to an uneven distribution of weight causing parts of a rotating object (like a tire or drive shaft) to move unevenly, often resulting in vibration or uneven wear.
