Question 10 A state representative wishes to estimate the mean number of women representatives per state legislature. A random sample of 17 was selected, and from the sample, the point estimate of the mean is 33.4, and the variance is 823.69, find the \( 90 \% \) confidence interval of the mean population. (write the upper limit for the confidence interval). Add your answer Integer, decimal, or E notation allowed Question 9 A state representative wishes to estimate the mean number of women representatives per state legislature. A random sample of 17 was selected, and from the sample, the point estimate of the mean is 33.4, and the variance is 823.69, find the \( 90 \% \) confidence interval of the mean population. (write the lower limit for the confidence interval). Add your answer Integer, decimal, or E notation allowed Question 9 A state representative wishes to estimate the mean number of women representatives per state legislature. A random sample of 17 was selected, and from the sample, the point estimate of the mean is 33.4, and the variance is 823.69, find the \( 90 \% \) confidence interval of the mean population. (write the lower limit for the confidence interval). Add your answer Integer, decimal, or E notation allowed \( 4 ( ( \frac { \sqrt { 3 } } { 2 } x - \frac { 1 } { 2 } y ) ^ { 2 } ) + ( 2 \sqrt { 3 } ( \frac { \sqrt { 3 } } { 2 } x - \frac { 1 } { 2 } y ) ( \frac { 1 } { 2 } x + \frac { \sqrt { 3 } } { 2 } y ) ) + 2 ( ( \frac { 1 } { 2 } x + \frac { \sqrt { 3 } } { 2 } y ) ^ { 2 } ) + 10 \sqrt { 3 } ( \frac { \sqrt { 3 } } { 2 } x - \frac { 1 } { 2 } y ) + 10 ( \frac { 1 } { 2 } x + \frac { \sqrt { 3 } } { 2 } y ) = 5 \) Question 9 A state representative wishes to estimate the mean number of women representatives per state legislature. A random sample of 17 was selected, and from the sample, the point estimate of the mean is 33.4, and the variance is 823.69, find the \( 90 \% \) confidence interval of the mean population. (write the lower limit for the confidence interval). Add your answer Integer, decimal, or E notation allowed Find \( \frac{d y}{d x} \) for \( y=\tan ^{-1}\left\{\frac{\sqrt{1+x^{2}}+\sqrt{1-x^{2}}}{\sqrt{1+x^{2}}-\sqrt{1-x^{2}}}\right\} \) Question 6 find \( P(Z<-1.23) \) Add your answer Integer, decimal, or E notation allowed If a function \( f(x) = 3x + 2 \), what is its inverse function? Question 5 The final exam scores in a statistics class are normally distributed with a mean of 63 and a standard deviation of 5. \( 30 \% \) of the students scored more than what value? Add your answer Integer, decimal, or E notation allowed ВИКОНАЙТЕ ДІЇ НАД МНОЖИНАМИ \( (C \cup B) /(C \cap A) \), якщо \( A=\{1,-3,2,7,8\} \quad B=\{0,7,8,-3\} \quad C=\{0,2,1,4\} \).
