Researchers investigated the effectiveness of oral zinc, as compared to a placebo, in reducing the found those taking oral durat
MaRussiya [10]

Answer: none of the above

Step-by-step explanation: when performing an hypothesis test and we want to make conclusion by comparing the p-value with the level of significance α

When p is greater than α, we reject the null hypothesis because it simply implies that we have a larger chance to commit a type 1 error ( α is the probability of committing a type 1 error an error where we reject the null hypothesis instead of accepting it ) which means we reject the null hypothesis.

When p is lesser than level of significance α, it means that we have a lesser chance of committing a type 1 error, which means we accept the null hypothesis.

I If the game with 3 hits is considered to be recorded in error, it might be removed from the data set. If that happens a. What
Flura [38]

Answer:

If the game with 3 hits is ignored the data becomes:

  • 7, 7, 8, 8, 8, 8, 9, 9, 9, 9, 9, 10, 10, 10, 10, 11, 11, 11, 11

a) The mean will increase.

<u>With 3:</u>

  • (3 + 7*2 + 8*4 + 9*5 + 10*4 + 11*4)/20 = 8.9

<u>Without 3:</u>

  • (7*2 + 8*4 + 9*5 + 10*4 + 11*4)/19 = 9.21

b) The median will remain as is.

  • With 3 and without the median is same = 9

Home Videos Inc. surveys 450 households and finds that the mean amount spent for renting or buying videos is P135 a month and th
adell [148]

SOLUTION:

Case: Hypothesis testing

Step 1: Null and Alternative hypotheses

\begin{gathered} H_0:\mu=P127.50 \\ H_1:\mu\leq P127.50 \end{gathered}

Step 2: T-test analysis

\begin{gathered} t=\frac{\hat{x}-\mu}{\frac{s}{\sqrt{n}}} \\ t=\frac{135-127.5}{\frac{75.25}{\sqrt{450}}} \\ t=2.144 \end{gathered}

Step 3: t-test with the significance level

\begin{gathered} t_{\alpha}=? \\ \alpha=0.05 \\ From\text{ }tables \\ t_{0.05}=1.654 \end{gathered}

Step 4: Comparing

t>t_{\alpha}

So tail to reject the null hypothesis. There is enough evidence at a 0.05 level of significance to claim that the mean spent is greater than P127.50.

Final answer:

Yes, there is evidence sufficient to conclude that the mean amount spent is greater than P127.50 per month at a 0.05 level of significance.

8. Math on the Spot Write an equation in slope-intercept form for the line that passes
PolarNik [594]

Answer: y=-x-1

Step-by-step explanation:

To find the answer, 5 and -6 have to be substituted in the place of x in the equation y = -x + b(The slope has to be the same because the line is parallel). -6 = -5 + b, b = -1. This means that the equation is y = -x - 1.
