Experiments on learning in animals sometimes measure how long it takes mice to find their way through a maze. The mean time is 1

Dahasolnce [82]

Answer:

<h3>Option c) $H_a:\mu$ is correct</h3><h3>The alternate hypothesis for the significance test is $H_a:\mu$ </h3>

Step-by-step explanation:

The alternate hypothesis use the sumbol for the population value

Let p be the proportion , Mean be $\mu$ and stadard deviation be $\sigma$

The null hypothesis states that population value is equal to the value mentioned in the given claim.

$H_0:\mu=18$ (by given).

The alternate hypothesis for the significance test states that the opposite of the null hypothesis(based on the claim )

∴ $H_a:\mu$

The symbol "<" because we want to test if the maze is completed faster and thus if the time has decreased.

<h3>∴ option c) $H_a:\mu$ is correct.</h3>

What is a solution to 4x+6<(with a line under it ) 18

JulsSmile [24]

Answer:

$\textbf{$x \in (-\infty, 3] $}\\$

Step-by-step explanation:

$\textup{Given:}\\$ 4x + 6 $\textup{Subtracting $6$ from both the sides }\\$ 4x \leq 18 - 6 \hspace{5mm} (=12) $\\\textup{Dividing by $4$ on both the sides: \hspace{15mm} [Note that the sign of the inequality changes only when we divide it by a negative number]}\\$$ x \leq 3 $$\\\textup{$x$ can be any real number less than or equal to 3.}\\$ \iff x \in R^- \cup \{a : 0 \leq a \leq 3\} $$
