When it is raining outside, you tend to stay in and watch tv. the number of hours of tv that you watch in a given week is twice the number of rainy days in that week. in the equation below, y is the number of hours of tv you watch in a week, and x is the number of rainy days in that week. the relationship between these two variables can be expressed by the following equation: y=2x identify the dependent and independent variables.

The independent is rainy days and the dependent should be hours of tv.

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
