How long would the toy car be?...

maks197457 [2]

Answer:

6.37 cm.

Step-by-step explanation:

Since Hot Wheels uses a scale ratio of 1:64 (1 cm to scale = 64 cm actual) for their toys, knowing that the actual length of a VW Beetle is 160.6 inches, to determine the length of the toy car is you must perform the following calculation:

1 inch = 2.54 cm

(160.6 x 2.54) / 64 = X

407.924 / 64 = X

6.373 = X

Therefore, the size of the toy car will be 6.37 cm long.

Consider the estimated equation from Example 4.3, which can be used to study the effects of skipping class on college GPA: 2 col

Answer:

Step-by-step explanation:

1) The confidence interval is calculated as the following

$CI = ( \bar x-1.96 \sigma ,\bar x=1.96 \sigmam)$

$= (0.412-1.96 \times 0.094, 0.412 = 1.96 \times 0.094)\\\\= (0.22776, 0.59624)$

Hence, the confidence interval is $0.22776 \leq \beta_G_P_A \leq 0.59624)$

11) Under two sid t-tailed test, the null hypothesis

$H_0; \beta_{GPA}=0.4$

Against the alternative hypothesis

$H_1 ; \beta _{GPA} \neq 0.4$

Under null hypothesis

$t = \frac{\hat \beta _1 - \beta _1}{Se( \beta _1)} \\\\ =\frac{0.412-0.4}{0.094} \\\\=0.12766$

The degree of freedom is n - 1 = 140

From the t - table at 5% level of significance under two - tail is 1.96

Since , calculated value is lowe than the tabulated value, we do not reject the null hypothesis.
