- Find the mean hourly cost when the cell phone described above is used for 240 minutes.Use your model to predict the sunspot number for 2001. How does your prediction compare with the actual value of 111?Last year, 58% of butterflies in NC were monarchs. We hypothesize that the proportion changed this year (Hint: I said "changed", not greater or less than! Also, the word proportion is a hint on which test to use in your calculator). We do a study of 250 butterflies and 170 were monarchs. Use an alpha = 0.05 Find the p-value. Write it in standard form or as an exponent.
- 5/6.2 I NEED TO SEE EXPLANATION PLEASE!!?A CBS News poll conducted June 10 and 11, 2006, among a nationwide random sample of 651 adults, asked those adults about their party affiliation (Democrat, Republican or none) and their opinion of how the US economy was changing ("getting better," "getting worse" or "about the same"). The results shown in the table below. Express your answers as a decimal and round to the nearest 0.001 (in other words, type 0.123, not 12.3% or 0.123456). If we randomly select one of the adults who participated in this study, compute: P(affiliated with neither party) = P(worse) = P(worse | affiliated with neither party) = P(affiliated with neither party worse) = P(affiliated with neither party and worse) =Between z= 1.42 and z= 2.17
