pychu [463]

Answer:

B. 15

Step-by-step explanation:

The chances of randomly selecting keys for a sports car or convertible is 5/40 since there are a total of 5 sports and convertible car keys and a total of 40 keys overall. We then multiply that 5/40 by 120 because Sam randomly selects a key 120 times.

5/40 × 120 = 15

Find the critical value tc for the confidence level cequals 0.95 and sample size nequals 19.

Alex_Xolod [135]

The critical values are fixed values which can be obtained from the standard t crit tables. We can find the critical value tc when the degrees of freedom and confidence level are given. The degrees of freedom is simply:

Degrees of Freedom = Number of samples – 1

Degrees of Freedom = 19 – 1

Degrees of Freedom = 18

From the t critical tables, the tc corresponding to Degrees of Freedom equal to 18 and Confidence level equal to 95% is as follows:

tc = 2.101

Therefore this means that any t value beyond 2.101, we already reject the null hypothesis.
