William used a sample of 68 large U.S. cities to estimate the relationship between Crime (annual property crimes per 100,000 per

sons) and Income (median annual income per capita, in dollars). His estimated regression equation was Crime= 428 + 0.050 Income. We can conclude that:
a. crime seems to create additional income in a city.

b. the slope is small so Income has no effect on Crime.

c. the intercept is irrelevant since zero median income is impossible in a large city.

d. wealthy individuals tend to commit more crimes, on average.

The weight of a USB flash drive is 30 grams and is normally distributed. Periodically, quality control inspectors at Dallas Flas
vazorg [7]

Answer:

The critical t values are -1.746 and 1.746.

Step-by-step explanation:

Given information:

The weight of a USB flash drive is 30 grams and is normally distributed.

Population mean = 30

Sample size = 17

Sample mean= 31.9

Standard deviation = 1.8

Significance level, α=0.10

Null hypothesis: H_0:\mu=30

Alternative hypothesis: H_1:\mu\neq 30

It is a two tailed test.

The t-critical values for a two-tailed test, for a significance level of α=0.1 are  -1.746 and 1.746.

Therefore the critical t values are -1.746 and 1.746.
