B. Read the paragraph below and look for examples of irony. Then, tell what kind of irony was employed. Gay tried her best to take care of her little sister's (Lala) pet fish while Lala was away for a school trip. On the second day, Gay found the fish floating belly up on the morning that Lala was to return from the trip. Not wanting Lala to experience the grief that comes with the fish's passing, Gay went to the pet store and bought a fish that looked a lot like Lala's. Unfortunately, Gay had not noticed the tiny white spot on the tail of the new fish. When the small girl was reunited with her pet, she immediately asked, "Sis-Gay, how did Mr. Wacks' tail get a little white spot?" The question caught Gay off guard. She looked around nervously and the seconds were tense, but she soon recovered. "Well, Lala, Mr. Wacks must have wiped some of his orange coat off on the rocks at the bottom of his bowl." The little girl was content with the answer but emptied all of the rocks from the fishbowl the following day to prevent Mr. Wacks from losing anymore his beautiful coat. Which type of irony was used? $ \qquad $ Explain your answer: $ \qquad $ $ \qquad $

Length of 7 observations measured constructed at 98\% condence interval for a mean value and variance of their height, assuming that the length comes from a normal distribution. $N(\mu, \sigma^2)$, both parameters unknown. 98\% CI for $\mu$ in cm: (c; 115.699) 98\% CI for $\sigma^2$ in $cm^2$: (d; 368.998) The length of the first six observations in centimeters is: 118.1, 113.0, 109.7, 106.0, 104.3, and 101.9. Determine missing values of lower bounds of the confidence intervals $c \in R$ and $d \in R$. What is the length of last observation?
