Solution Steps

Step 1: Understand the Conversion Formula

To convert a temperature from Celsius to Fahrenheit, we use the formula: \[ F = \frac{9}{5}C + 32 \] where \( F \) is the temperature in Fahrenheit and \( C \) is the temperature in Celsius.

Step 2: Substitute the Given Temperature

The given temperature in Celsius is \( -63^{\circ} \mathrm{C} \). Substitute this value into the formula: \[ F = \frac{9}{5}(-63) + 32 \]

Step 3: Perform the Multiplication

First, calculate the multiplication: \[ \frac{9}{5} \times (-63) = -113.4 \]

Step 4: Add 32 to the Result

Next, add 32 to the result of the multiplication: \[ -113.4 + 32 = -81.4 \]

Final Answer

The temperature in Fahrenheit is: \[ \boxed{-81.4^{\circ} \mathrm{F}} \] Thus, the correct answer is \(-81.4^{\circ} \mathrm{F}\).

A certain drug is used to treat asthma. In a clinical trial of the drug, 29 of 283 treated subjects experienced headaches (based on data from the manufacturer). The accompanying calculator display shows results from a test of the claim that less than 11% of treated subjects experienced headaches. Use the normal distribution as an approximation to the binomial distribution and assume a 0.01 significance level to complete parts (a) through (e) below. C. H0: p=0.11 D. H0: p ≠ 0.11 Decide whether to reject the null hypothesis. Choose the correct answer below. A. Reject the null hypothesis because the P-value is greater than the significance level, α. B. Fail to reject the null hypothesis because the P-value is less than or equal to the significance level, α. C. Fail to reject the null hypothesis because the P-value is greater than the significance level, α. D. Reject the null hypothesis because the P-value is less than or equal to the significance level, α. e. What is the final conclusion? A. There is sufficient evidence to support the claim that less than 11% of treated subjects experienced headaches. B. There is not sufficient evidence to support the claim that less than 11% of treated subjects experienced headaches. C. There is not sufficient evidence to warrant rejection of the claim that less than 11% of treated subjects experienced headaches. D. There is sufficient evidence to warrant rejection of the claim that less than 11% of treated subjects experienced headaches.

Here are summary statistics for randomly selected weights of newborn girls: n=36, x̄=3150.0 g, s=695.5 g. Use a confidence level of 95% to complete parts (a) through (d) below. b. Find the margin of error. E=227.2 g (Round to one decimal place as needed.) c. Find the confidence interval estimate of μ. 2922.8 g<μ<3377.2 g (Round to one decimal place as needed.) d. Write a brief statement that interprets the confidence interval. Choose the correct answer below. A. One has 95% confidence that the sample mean weight of newborn girls is equal to the population mean weight of newborn girls. B. Approximately 95% of sample mean weights of newborn girls will fall between the lower bound and the upper bound. C. One has 95% confidence that the interval from the lower bound to the upper bound contains the true value of the population mean weight of newborn girls. D. There is a 95% chance that the true value of the population mean weight of newborn girls will fall between the lower bound and the upper bound.
