Instruction: DO NOT use the T-table, use the invt( ) program available in your calculator to calculate the tvalue. Round \( t_{c} \) to 3 decimal places and margin of error to 2 decimal places. A) A sample of 12 hummingbirds was randomly selected and gave a mean weight of \( 3.14 \) and standard deviation of \( 0.34 \) grams. Find the \( 92 \% \) confidence interval to estimate the population mean weight of hummingbirds. D. \( F .= \) \[ t_{c}= \] C.I. : \( 3.14 \pm \) B) A sample of 20 hummingbirds was randomly selected and gave a mean weight of \( 3.11 \) and standard deviation of \( 0.33 \) grams. Find the \( 98 \% \) confidence interval to estimate the population mean weight of hummingbirds. D. \( F .= \) \[ t_{c}= \] C.I. : \( 3.11 \pm \) C) A sample of 90 hummingbirds was randomly selected and gave a mean weight of \( 3.14 \) and standard deviation of \( 0.34 \) grams. Find the \( 95 \% \) confidence interval to estimate the population mean weight of hummingbirds. D. \( F_{\text {. }}= \) \[ t_{c}= \] \[ \text { C.I. : } 3.14 \pm \]
