Answer:

Decimals can be written in fraction form. To convert a decimal to a fraction, place the decimal number over its place value. For example, in 0.6, the six is in the tenths place, so we place 6 over 10 to create the equivalent fraction, 6/10. If needed, simplify the fraction.

d = ?

<h3>Solution</h3>

<u>Formula for the terms of AP:</u>

a4 = a + 3d
a2 = a + d

<u>The difference of terms:</u>

a + 3d - (a - d) = 13 - 3
2d = 10
d = 5

One of your friends is testing the effect of drinking coffee on the duration of cold symptoms. The common cold lasts, on average

Nonamiya [84]

Answer:

0.0930

Step-by-step explanation:

Given that one of your friends is testing the effect of drinking coffee on the duration of cold symptoms. The common cold lasts, on average, 6 days.

she tests a one-sided alternative about the population mean cold duration when drinking coffee, H0: μcoffee = 6 Ha: μcoffee < 6 She finds z = −1.68 with one-sided P-value P = 0.0465.

If hypotheses changed to two tailed as:

$H_0: \mu_{coffee} = \mu_{tea}\\H_a: \mu_{coffee}\neq \mu_{tea}$

(Two tailed test)

Since we have mean difference and std error the same, test statistic would remain the same.

p value for two tailed would be = twice the p value for one tail

= $2(0.0465)\\= 0.0930$
