Answer:
The average for the sampling distribution of the sample proportion is 0.29
The standard deviation for this sampling distribution is 0.01435
Step-by-step explanation:
The mean of the sampling distribution for the sample proportion equals the actual population proportion, which is p = 0.29 in this scenario.
The standard deviation for the sampling distribution of the sample proportion is computed as follows;

Utilizing the provided values;
p = 0.29
1 - p = 0.71
n = 1000
The standard deviation computes to;

Thus, the standard deviation is 0.01435.
Answer:
The type of analysis that does not aid in determining if the rise in sales is statistically significant is calculating the prediction's precision.
Step-by-step explanation:
"A sales promotion involves features via advertisements and/or discounted pricing for a specific product or service."
First, combine the solution and salt: 120 liters + 80 liters = 200 liters. The percentages average out: 5% + 15% = 20%. Therefore, the ratio is 20:200, leading to a concentration calculation of 20/200 = 0.10. Ultimately, the final concentration is 10% salt.
The formula to convert Fahrenheit to Celsius is:
Celsius = (Fahrenheit - 32) x 5/9
C(76.1) = (76.1 - 32) x 5/9
= (44.1) x 5/9
= 24.5
Hence, 76.1°F is equal to 24.5°C.
