A computer manufacturer estimates that its cheapest screens will last less than 2.8 years. A random sample of 61 of these screens has a mean life of 2.7 years. The population is normally distributed with a population standard deviation of 0.88 years. At =0.02, can you support the organization's claim using the p-value?
No, the claim cannot be supported. The p-value is 0.81, it is greater than = 0.02, we fail to reject the null, the claim is the alternate hypothesis and is not supported.
Yes, the claim can be supported. The p-value is 0.37, it is less than = 0.02, we reject the null, the claim is the alternate and is supported.
Yes, the claim can be supported. The p-value is 0.01, it is less than = 0.02, we reject the null, the claim is the alternate and is supported.
No, the claim cannot be supported. The p-value is 0.18, it is greater than = 0.02, we fail to reject the null, the claim is the alternate hypothesis and is not supported.
