Para determinar el dominio de la función \( t𝑓(𝑥) = \frac{𝑥 – 3}{𝑥^2 + 6𝑥 − 16} \), necesitamos encontrar el conjunto de todos los valores posibles de \( x \) que hará que la función esté definida. Esto significa que necesitamos identificar cualquier valor de \( x \) que causaría que el denominador sea cero, ya que la división por cero no está definida. El denominador de la función es una expresión cuadrática \( 𝑥^2 + 6𝑥 − 16 \). Para encontrar los valores de \( x \) que hacen que el denominador sea cero, podemos factorizar la cuadrática: 𝑥^2 + 6𝑥 − 16 = (𝑥 + 8)(𝑥 - 2) Igualar cada factor a cero nos da los valores de \( x \) que no están permitidos: 𝑥 + 8 = 0 \quad \Rightarrow \quad 𝑥 = -8 𝑥 - 2 = 0 \quad \Rightarrow \quad 𝑥 = 2 Por lo tanto, el dominio de la función \( t𝑓(𝑥) \) son todos los números reales excepto \( x = -8 \) y \( x = 2 \). En notación de intervalo, el dominio es: (-\infty, -8) \taza (-8, 2) \taza (2, \infty) Esto significa que la función \( t𝑓(𝑥) \) está definida para todos los números reales excepto \( x = -8 \) y \( x = 2 \).

The boxplot below is of the sodium contents levels taken from a random sample of 30 bottles. With this data investigate the claim using SPSS to apply the appropriate test. Download the data and transfer it into SPSS. Check that your data transfer has been successful by obtaining the Std. Error of the mean for your data which should appear in SPSS output as 0.03900.. If you do not have this exact value, then you may have not transferred your data from the Excel file to SPSS correctly. Do not continue with the test until your value agrees as otherwise you may not have correct answers. Unless otherwise directed you should report all numeric values to the accuracy displayed in the SPSS output that is supplied when your data has been transferred correctly. In the following questions, all statistical tests should be carried out at the 0.05 significance level. Sample mean and median Complete the following concerning the mean and median of the data. mean =  mg/L 95% CI:  to  mg/L Based upon the 95% confidence interval, is it plausible that the average sodium content is 36.9 mg/L?      median:  mg/L The median value is      36.9 mg/L. Skewness Complete the following concerning the skewness of the data. Skewness statistic =        Std. Error =  The absolute value of the skewness statistic     less than 2 x Std. Error Therefore the data can be considered to come from a population that is      . Normality test Complete the following summary concerning the formal testing of the normality of the data. H0: The data come from a population that     normal H1: The data come from a population that     normal Application of the Shapiro-Wilk test indicated that the normality assumption     reasonable for sodium content (S-W(  )=  , p=   ). Main test Using the guidelines you have been taught that consider sample size, skewness and normality, choose and report the appropriate main test from the following ( Appropriate ONE ) You have selected that you wish to report the one-sample t-test. H0: The mean sodium content     equal to 36.9 mg/L H1: The mean sodium content     equal to 36.9 mg/L Application of the one-sample t-test indicated that the mean is      36.9 mg/L (t(  ) =  , p =   ). You have selected that you wish to report the Wilcoxon signed rank test. H0: The median sodium content     equal to 36.9 mg/L H1: The median sodium content     equal to 36.9 mg/L Application of the Wilcoxon signed rank test indicated that the median is      36.9 mg/L (z =  , N =  , p =   ).
