Answer:

The value is $p- value = 0.041815$

Step-by-step explanation:

From the question we are told that

The population mean is $\mu = 40 \ hours$

The sample size is $n = 18$

The sample mean is $\= x = 37.8 \ hours$

The standard deviation is $\sigma = 5.4\ hours$

The null hypothesis is $H_o : \mu = \ge 40$

The alternative hypothesis is $H_a : \mu < 40 \ hour s$

Generally the test statistic is mathematically evaluated as

$t= \frac{\= x - \mu}{ \frac{\sigma}{ \sqrt{n} } }$

$t= \frac{37.8 - 40}{ \frac{5.4}{ \sqrt{18 } }$

$t= -1.73$

From the z - table the p-value is obtained and the value is

$p- value = P(Z < -1.73)$

$p- value = 0.041815$

Which graph represents a degree three polynomial function with a negative leading<br> coefficient?

Vadim26 [7]

The graph of a 5th-degree polynomial with a negative leading coefficient will start at (-∞, +∞) and end at (+∞, -∞). That is, it will have the overall shape \, downward from left to right. Along the way, it may change direction 0, 2, or 4 times, and may intersect the x-axis up to 5 times.

Only one of the graphs shown has the described end behavior. All of the others have the general shapes ...
