Steve, who lives in England, is reading a letter from his pen pal in the United States. His pen pal says that the temperature in his city was 37.4° Fahrenheit one day, so it was too cold to play rugby outside. Steve doesn't know how cold this is, because he is used to temperatures in Celsius. Help Steve solve the following equation to determine the temperature in degrees Celsius: 1.8C+32=37.4. Round your answer to the nearest tenth of a degree.

Hello There!

1.8C+32=37.3

1.8C=37.3-32

1.8C=5.3

Now divide both sides by 1.8 to isolate C:

C=2.9

Hope this helps!

( 67.18, 68.82)

Step-by-step explanation:

Let be the true (population) mean of statistics exam scores. We have a large random sample of n = 36 scores with a sample mean (sample mean score) of . We know that the population standard deviation is . A pivotal quantity is which is approximately normally distributed and where , and so, . Therefore the 90% confidence interval is (68-(1/2)(1.6449), 68+(1/2)(1.6449)), i.e., ( 67.18, 68.82)
