Answer 1

Mathematical symbol of the alternative hypothesis of the statement:

Statements square measure written with the alternative hypothesis image square measure known alternative hypothesis & denoted as $H_{a}$.

Alternative hypothesis symbol :

i)   Equal ( = ), not up to ( $\neq$ )

ii)  Greater than or up to ( $\geq$ )

iii) Less than or up to ( $\leq$ )

$\displaystyle 1) H_{1} \neq 14\\\\\displaystyle 2) H_{2} = 40\\\\\displaystyle 3) H_{3} = 15 \\\\\displaystyle 4) H_{4} = 35\\\\\displaystyle 5) H_{5} = 8\\\\\displaystyle 6) H_{6} \leq 5\\\\\displaystyle 7) H_{7} \geq \frac{1}{2} \\\\\displaystyle 8) H_{8} = 45\\\\\displaystyle 9) H_{9} =55\\\\\displaystyle 10) H_{10} = 14$
