Problem 5E

Crash testing is a highly expensive procedure to evaluate the ability of an automobile to withstand a serious accident. A simple random sample of 12 small cars were subjected to a head-on collision at 40 miles per hour. Of them 8 were “totaled,” meaning that the cost of repairs is greater than the value of the car. Another sample of 15 large cars were subjected to the same test, and 5 of them were totaled. Find a 95% confidence interval for the difference in the proportions of small cars and large cars that are totaled.

Step-by-Step Solution:
Step 1 of 3

Berlo’s SMCR Model Sender- person who initiates communication Message- information to be sent Channel- how the information will be sent Receiver- intended audience for information encoding- how the sender translates their meaning into information decoding- how the receiver interprets the info based on the meaning feedback- response from receiver, signals to the sender degree to which info was not received synchronous communication- • communicate directly, at the same time • face to face asynchronous communication- • communicate indirectly, different times • voicemail, email, letter Types of noise Mechanical • affects the channel ◦ audible noise ◦ vague information for channel ◦ inappropriate channel for message
