1 answer:
Goshia [24]4 years ago

Answer:

Question 1:

(A) 22.5 weeks

Question 2:

(A) 35

Step-by-step explanation:

Question 1:

Given:

The line of best fit is given as:

y=1.12x+28.78

Where,

x\to age\ in\ weeks\\\\y\to height\ in\ centimeters

Height of the puppy (y) = 54 cm

Now, plug in the value of 'y' and solve for 'x'. This gives,

54=1.12x+28.78\\\\54-28.78=1.12x\\\\25.22=1.12x\\\\x=\frac{25.22}{1.12}=22.5\ weeks

Therefore, the puppy was 22.5 weeks old when he was 54 cm tall.

Question 2:

The line of best fit is given as:

y=0.32x-20.51

Where,

x\to number\ of\ times\ at\ bat\\\\y\to number\ of\ hits

Number of times at bat (x) = 175

Now, plug in the value of 'x' and solve for 'y'. This gives,

y=0.32\times 175-20.51=35.49\approx 35

Therefore, the number of hits is 35 to the nearest whole number.

Consider the following hypothesis test.H0:μ1−μ2=0 Ha:μ1−μ2≠0The following results are for two independent samples taken from the
Julli [10]

Answer:

a) z =\frac{104-106}{\sqrt{\frac{8.4^2}{80} +\frac{7.6^2}{70}}}= -1.53  

b) p_v =2*P(z

c) Since the p value is higher than the significance level provided we have enogh evidence to FAIL to reject the null hypothesis and we can't conclude that the true means are different at 5% of significance

Step-by-step explanation:

Information given

\bar X_{1}= 104 represent the mean for 1

\bar X_{2}= 106 represent the mean for 2

\sigma_{1}= 8.4 represent the population standard deviation for 1

\sigma_{2}= 7.6 represent the population standard deviation for 2

n_{1}=80 sample size for the group 1

n_{2}=70 sample size for the group 2

z would represent the statistic

Hypothesis to test

We want to check if the two means for this case are equal or not, the system of hypothesis would be:

H0:\mu_{1}=\mu_{2}

H1:\mu_{1} \neq \mu_{2}

The statistic would be given by:

z =\frac{\bar X_1-\bar X_2}{\sqrt{\frac{\sigma^2_1^2}{n_1} +\frac{\sigma^2_2^2}{n_2}}}=(1)

Part a

Replacing we got:

z =\frac{104-106}{\sqrt{\frac{8.4^2}{80} +\frac{7.6^2}{70}}}= -1.53

Part b

The p value would be given by this probability:

p_v =2*P(z

Part c

Since the p value is higher than the significance level provided we have enogh evidence to FAIL to reject the null hypothesis and we can't conclude that the true means are different at 5% of significance

A researcher investigates if chocolate affects mood. She recruits college students to take a mood inventory, ingest a quarter po
Nookie1986 [14]

Answer:

A) Reject the null hypothesis and conclude that chocolate affected mood because zero, or no effect, does not fall within the confidence interval

Step-by-step explanation:

The confidence interval could be used as a tool to test an hypothesis on a some certain conditions. When we obtain a confidence interval whose range includes the value 0, we would fail to reject the null hypothesis of such analysis as this upholds the truth of the null hypothesis. However, if the interval does not contain the value 0, we reject the null and claim that there is significant evidence to accept the alternative hypothesis.

Hence, for the confidence interval given [2.34, 5.41], the interval does not contain the value 0, Hence, we reject the null.
