7 0

The p-value falls between 0.025 and 0.05 is my guess, since we have t = -1.45 in 25 observations. The test of H0 against Ha show that μ = 7.2 and μ < 7.2 means μ = μ (7.2 = 7.2).

Answer:

almost 0%

Step-by-step explanation:

Given that for an insurance company with 10000 automobile policy holders, the expected yearly claim per policyholder is $240 with a standard deaviation of 800

using normal approximation, the probability that the total yearly claim exceeds $2.7 million is calculated as follows:

Sea sumatoria de x = SUMX, tenemos que:

$P (SUMX \geq 2700000) = P(\frac{SUMX - 240*10000}{800 *\sqrt{10000} } \geq \frac{2700000 - 240*10000}{800 *\sqrt{10000} })$
