question 122

Multiple Choice

Use the given degree of confidence and sample data to construct a confidence interval for the population mean µ. Assume that the population has a normal distribution.
-Weights of eggs: $95 \%$ confidence; $\mathrm { n } = 22 , \overline { \mathrm { x } } = 1.77 \mathrm { oz } , \mathrm { s } = 0.47 \mathrm { oz }$

• A) \(0.36 \mathrm { oz } < \sigma < 0.65 \mathrm { oZ }\)
• B) \(0.37 \mathrm { oz } < \sigma < 0.61 \mathrm { oz }\)
• C) \(0.36 \mathrm { oz } < \sigma < 0.67 \mathrm { oz }\)
• D) \(0.38 \mathrm { oz } < \sigma < 0.63 \mathrm { oz }\)

Definitions:

Myosin Heads

The part of the myosin protein that binds to actin filaments and performs the power stroke to cause muscle contraction.

Cross-Bridges

The connections formed between actin and myosin filaments in muscle fibers during contraction.

Actin Myofilaments

Thin filaments within muscle cells that, along with myosin, contribute to muscle contraction and relaxation.

Threshold Level

A threshold level refers to the minimum intensity that stimulates a perceptible response in a physical, biological, or psychological system.
