Chapter 10: Q. 68 (page 600)

Use the following information to answer next five exercises. A study was conducted to test the effectiveness of a juggling class. Before the class started, six subjects juggled as many balls as they could at once. After the class, the same six subjects juggled as many balls as they could. The differences in the number of balls are calculated. The differences have a normal distribution. Test at the \(1 \%\) significance level.

State the null and alternative hypotheses.

Short Answer

Expert verified

The null and alternative hypotheses are given as,

H0:μafter-μbefoe≥0H1:μafter-μbefore<0

Step by step solution

01

Given information

The table is

02

Step 2: State the null and alternative hypotheses.

The mean number of balls that were juggled before class was μbefore.

Also, the mean number of balls that were juggled after class was μafter.

The null and alternative hypothesis is:

localid="1652950591203" H0:μafter-μbefoe≥0H1:μafter-μbefore<0

Draw the graph of the p-value.

In a random sample of 100 forests in the United States, 56 were coniferous or contained conifers. In a random sample of 80 forests in Mexico, 40 were coniferous or contained conifers. Is the proportion of conifers in the United States statistically more than the proportion of conifers in Mexico?

Use the following information to answer the next five exercises. A study was conducted to test the effectiveness of a software patch in reducing system failures over a six-month period. Results for randomly selected installations are shown in Table 10.21. The “before” value is matched to an “after” value, and the differences are calculated. The differences have a normal distribution. Test at the 1% significance level.
