Step-by-step explanation:
To make it easy to read very large and small numbers, we write them in standard form. Any number that we can write as a decimal number, between 1.0 and 10.0, multiplied by a power of 10, is said to be in standard form. 1.98 ✕ 10¹³; 0.76 ✕ 10¹³ are examples of numbers in standard form.
Answer:
a. remain the same
b. decrease
c. remain the same
d. t decreases
the answers are in bold letters under each question. Thank you
Step-by-step explanation:
a. A switch from using a two-tailed test to a one-tailed test
A switch from 2 tailed test to one tailed test will have t statistic <em><u>remain the same</u></em>. This does not change the value of t statistic
b. An increase in the sample variance (s^2)
when sample variance s^2 is increased, we will have it that standard error has increased. therefore t statistic will<u> </u><em><u>decrease</u></em>
c. An increase In the significance level (such as using α= 0.05 instead of σ= 0.02)
t statistics will <em><u>rema</u><u>in</u><u> the</u><u> same</u></em><em><u>.</u></em><em><u> </u></em>this is due to the fact that significance level is not a part of the t statistics formula.
d. A decrease in the sample Size (n)
when sample size is decreased, standard error will increase. therefore t statistic will <em><u>decrease</u></em><em><u>.</u></em>
